우리나라가 속해 있는 동북아지역은 동남아시아와 더불어 세계 물류의 중심지 및 생산공장의 역할을 수행하고 있다. 특히 동북아시아를 선도하고 있는 한국, 중국, 일본의 경우 동아시아의 물류 거점역활 선점과 글로벌기업 유치를 위하여 다양한 Free Zone제도를 제정 도입하여 활성화에 노력을 기울이고 있다. 이러한 상황에서 동 제도의 시행초기 단계에 있는 우리나라의 경우, 주변국을 벤치마킹하여 성공요인을 찾는 것이 시행착오를 줄이고 경쟁의 우위를 확보하는 지름길이 될 것이다. 한편, 주변국의 Free Zone들은 다양한 전략을 가지고 경쟁을 하고 있으나, 우리나라의 경우 자유무역지대 활성화 전략에 포함되는 구성요소간의 종속관계, 계층파악 등의 시스템 적인 차원에서의 접근은 전무한 실정이다. 따라서 본 논문은 이러한 점에 착안하여, 군산 자유무역지대(Free Trade Zone) 성공요인을 파악하고, 이를 바탕으로 하여 군산자유무역지대 활성화를 위한 구조모델을 FSM법을 사용하여 구축하는 것을 연구의 목적으로 하였다.

This paper reports the result of an investigation into wave propagation in orthotropic laminated piezoelectric cylindrical shells in hydrothermal environment. A dynamic model of laminated piezoelectric cylindrical shell is derived based on Cooper-Naghdi shell theory considering the effects of transverse shear and rotary inertia. The wave characteristics curves are obtained by solving an eigenvalue problem. The effects of layer numbers, thickness of piezoelectric layers, thermal loads and humid loads on the wave characteristics curves are discussed through numerical results. The solving method presented in the paper is validated by the solution of a classical elastic shell non-containing the effects of transverse shear and rotary inertia. The new features of the wave propagation in laminated piezoelectric cylindrical shells with various laminated material, layer numbers and thickness in hydrothermal environment and some meaningful and interesting results in this paper are helpful for the application and the design of the ultrasonic inspection techniques and structural health monitoring.

It is very important that we try to keep our traditional historical assets in the original form for a long time. Seoggur-Am has a very long and old history of about 1200 years. Yet, for the past several years there are many factors ruinning this historical treasure. Recently, specialist are new scientifically examining Seoggur-Am and evaluating its current condition, If you only judge these historical assets from the exterior structural environmental approach your scientific conclusion will not be complete. No one has studied Seoggur-Am from the viewpoint of indoor environmental climate. Therefore, I have surveyed and prepared a report of investigation as well as countermeasure so to understand the impact of indoor environmental climate on Seoggur-Am. The purpose of this paper is to first survey the existing research data based on exterior structural environment. Secondly, closely evaluate the new data of Seoggur-Am from the viewpoint of indoor environmental climate.

It is conducted that study on corner crack protection for various thermal environment in a flat panel display. Most of the consumer electronics consist of a plastic and a metal structure. And different properties of materials could cause failure of structural reliability due to the various operating temperatures. Especially for front bezel with thin and slender structure, the effect of temperature is significant, and the design for crack protection is crucial for thermal reliability of displays. In this study, it is prescribed the behavior of the front bezel in flat panel display for various operation temperatures and proposed design parameters to ensure the structural reliability of displays.

Precast segmental bridge columns (PSBC) are alternatives for monolithic cast-in-situ concrete columns in bridge substructures, with fast construction speed and structural durability. The analytical tool for common use is demonstrated applicable for seismic performance prediction of PSBCs through experiment conducted earlier. Then the analytical program was used for parameter optimization of PSBC configurations under reversal cyclic loading. Shear strength by pushover analysis was compared with theoretical prediction. Moreover, seismic response of PSBC with energy dissipation (ED) bars was compared with its no ED bar counterpart under three history ground acceleration records. The investigation shows that appropriate ED bar and post-tensioned tendon arrangement is important for higher lateral bearing capacity and good ductility performance of PSBCs.

The purpose of this paper is to develop an integrated environment system for finite element structural analysis using OOA(Object-Oriented Analysis) and OOD(Object-Oriented Design), with may reduce inconveniencies in use such as file input of macro command and improve lacks of graphic presentation in the established finite element analysis program. This paper is attempted to suggest an easy approach to object-oriented concept and convenient programming. Two languages are used together in this paper instead of single C++ language for the development of object-oriented program. : Visual Basic with CDK(Custom Development Kit), and Borland C++ with OWL(Object Windows Library).

It is the purpose of this study to abtain a basic information about how the users evaluate housing environment. The structural model of housing environment which is employed Repertory Grid Developmental Method is extracted. This model Is composed of 4 classifications : 1) psychological evaluation, 2) visual evaluation, 3) variation, 4) spaciousness.The extracted model can be expected to be used as follows : 1) It is to provide the knowlege of user's evaluation of housing enironment with designers so that they can explore the optimum solution in environ-mental design. 2) It will be an useful data for selecting an evaluation item in psychological evaluation study using SD(Semantic Differential)method. 3) On the physical experiments, it will be an useful data to select an evaluation item.

The study is based on the technology-organization-environment (TOE) model which, attempted to determine the factors that are going to influence ICT adoption. The proposed research model evaluates the interplay among technological context (IT infrastructure, system security, and user capacity), organizational context (top management commitment, and innovations strategies), environmental context (quick response to the external agencies, interactive network infrastructure, and competitive pressure) and ICT adoption (productivity growth, organizational change, and competitiveness). Data were collected from 243 senior executives of full member firms of the Bangladesh Garments and Manufacturers Association (BGMEA) of examining the relationships among the constructs in the proposed framework utilizing structural equation modeling (SEM). The analysis of TOE factors revealed that environmental, organizational, and technological factors have a significant impact on the successful implementation of ICT tools. The study also discusses implications for management practitioners.

본 연구는 e-저작권침해 일탈행위를 유발하는 원인을 규명하기 위해 진행되었다. 이를 위해 대학생 531명을 대상으로 설문을 실시하였고, 여기서 얻어진 데이터를 분석하기 위해서 구조방정식모델(SEM)을 사용하였다. 구조방정식모델의 설계는 익명상황, 규범의식, 처벌인지를 e-저작권침해에 대한 직접적인 변인으로 구성하였고, 또한 익명상황을 규범의식과 처벌인지에 대한 변인으로 설정하였다. 변인들 간의 직 간접적 인과관계를 분석한 결과, 익명상황은 e-저작권침해에 대한 직접적인 원인으로 나타났으나, 규범의식과 처벌인지 변인은 통계적으로 유의하지 않았다. 또한, 익명상황은 규범의식과 처벌인지에 대한 직접적으로 원인이며, 규범의식을 매개로 처벌인지에 간접적으로 영향을 미치는 것으로 밝혀졌다. 이러한 연구결과로 볼 때, e-저작권침해를 예방하기 위해서는 익명상황에서 규범을 지키는 것을 훈련할 수 있는 적절한 교육적 기회를 제공할 필요가 있다. 이를 위한 다양하고 효과적인 정보윤리 교육방법에 대한 모색이 이루어져야 할 것이다.
