웹사이트의 블로그에서 등록된 게시물을 분류, 표현하는 방식으로 카테고리 분류방식과 Tag cloud 분류방식을 사용하고 있다. 그러나 카테고리분류방식은 같은 게시물이라도 블로그 관리자별로 해당 분류의 생성기준이 주관적인 판단에 따라 다른 분류에 속할 수 있어 이용자들이 찾고자 하는 게시물을 검색하는데 많은 시간이 소요될 수 있다는 단점이 있다. 또한 이를 보완하는 방안으로 사용되는 Tag cloud 방식은 태그들을 흩어놓아 원하는 정보를 빠르게 찾는데 한계가 있다. 이에 본 논문은 블로그에서 태그들을 그룹화하여 구현한 트리형 Tag cloud(이하 'TreeTag cloud') 모델을 통해 카테고리 분류방식의 트리 구조의 장점인 직관성 및 구조화와 Tag cloud 분류방식의 장점인 짧은 search depth 를 결합하여 구현하는 방법을 제안하였다.

고속으로 발전하는 컴퓨터 분야에 있어서 소프트웨어는 좀더 복잡해지고 대형화 되어갔다. 이에 따른 소프트웨어의 테스팅은 소프트웨어 재사용성이나 유지보수, 오류 검출을 하기 위한 하나의 수단으로 사용되어져 가고 있으며, 보편화 되어가고 있다. 그리고 소프트웨어 개발 방법이 구조적 프로그래밍 기법에서 객체지향 프로그래밍 기법으로 변화할 수 옥 이에 따른 소프트웨어 테스팅 역시 구조적 프로그래밍 기법에서 사용하던 테스팅 방법들을 객체지향적 개념에 맞게 바꾸어 나가는 연구들이 많이 이루어지고 있다. 논문에서는 이러한 객체지향 테스팅 기법에서 사용하는 메트릭스들을 선정하여 이를 자바언어로 작성된 프로그램에 적용하고 그 결과물들을 그래픽컬한 표현으로 나타내어 편리한 테스트 환경을 지원하는 도구를 설계 및 구현하였다.

The aim of this study is to evaluate the design table for envelope curve analysis of base isolated buildings, which represent the period of base isolated buildings and the lateral displacement of base isolation devices. For the construction of design table, $V_E$ spectrum, which represents the energy, is developed instead of acceleration of seismic hazard. Based on the seismic coefficient of UBC 97, boundary period $T_G$ and maximum velocity response $V_0$ are proposed considering Korea seismic hazard. Using $T_G$ and $V_0$, finally, $V_E$ spectrum is developed for the four types of soil conditions. Base on the $V_E$ spectrum, design table for envelope curve analysis is also developed for soil types.

The purpose of this study is to analyse and interpret the way of differentiated expression and changing creative trend following 5-day workweek which has been recently adopted. For this aim 11 pieces of distinctive advertising text were analysed. The criteria for selection of analysing text were relativeness with 5-day workweek and cognitive inconsistency. These texts were negative phrases, exaggerated expression, and excessively humorous appeals. The study revealed the followings: First, 5-day workweek concerned advertising texts were considered as high attention getting and successful in stimulating advertising audiences' curiosity by using the elements opposing the value and belief system formed in the existing audience. Second, consumption-driving lifestyle was found in most expressions for credit cards advertising. Third, hedonic need-oriented lifestyle was typical in young consumer products category. Fourth, family centered lifestyle emphasized meaning of rest and solidarity of family.

The purpose of this study was to conduct the instruction for 'Family Life Planning' based on backward design and measured the learners' understanding and satisfaction for testing validity. In short, the result of this study are as follows: In this study, first of all, the students could explain significant concepts, knowledge, and principles for the planning of family life; they could interpret and apply them; they have perspectives on them; they could empathize them; and they could have self-knowledge. The students could also accomplish high achievements for important concepts related to the field of family life planning. In conclusion, this study showed that the developed instruction was very effective for the students to achieve fruitful results, accelerating the learners' persistent understanding. Second, the learners had high satisfaction on the instruction of Family Life Planning based on backward design with the average score of 3.68 out of the perfect score 4. The students could be satisfied with the developed instruction since they could have high interest in the class thanks to diverse learning materials, and they could take an active part in the learning tasks based on group activities and questions. Also they could apply the contents that they learned through task performances to new situation and context. Therefore, this study proved that the developed instruction enhanced the learners' satisfaction on class.

In the field of shape optimum design, much efforts are needed in regridding method and shape design sensitivity analysis. In this paper, Bezier curve is used to make the boundary of a structure and the improved direct differentiation method is used to calculate the shape design sensitivity. To regrid the finite element model, modified displacement field is presented in this paper. The modified displacement field makes more fine grid at large curvature. The purpose of this paper is to obtain the optimum shape of a cantilever with weight and a 3-dimensional journal bearing cap.

Extensive computer simulations to account for the randomness in the process of seismic demand estimation have been a serious obstacle to the adoption of probabilistic performance assessments for the decision of applying seismic intervention schemes. In this study, a method for rapid fragility assessments based on a response database and the fragility contour method are presented. By the comparison of response contours in different formats, it is shown that representing maximum responses in ductility demand is better for the investigation of the effect of structural parameter changes on seismic demands than representations in absolute values. The presented fragility contour enables designers to practically investigate the probabilistic performance level of every possible retrofit option in a convenient manner using visualized data sets. This example demonstrates the extreme efficiency of the proposed approach in performing fragility assessments and successful application to the seismic retrofit strategies based on limit state probabilities.

This study is an architectural design thesis aimed at designing a building at the River Thames in London, which could float along the river and be anchored in the river, in terms of the concept of the sense of place. The process of the study was as follows. First, theoretical backgrounds of the concepts of sense of place, placelessness, and non-place were examined and the sense of place of River Thames was analyzed. Second, the architectural planning elements could be applied to architectural design in terms of the relationship between the place and architecture, form of architecture, and behaviors of peoples. Third, the architectural design concepts and programs were specified based on the planning elements and a cultural complex that floats on the River Thames in London, England was proposed. The focus of this study was the process of formation of a sense of place by the cognition of architecture and people's activity, and this study claimed that the sense of place could be materialized by the metaphorically inherent property of the architecture.

In this study, structural behavior of bolted joints which were important elements in plate girder design was analyzed using commercial FE analysis program. Also, the numerical analysis method that simply showed behavior of bolts was proposed using the connector element of ABAQUS, nonlinear FE program. Numerical analysis was conducted to verify the proposed numerical analysis method on the basis of the experiment of previous study. In order to investigate effects of action force which was changed by locations of the bolted joints, the three different models were developed by the locations of the bolted joints and behavior for the each model was compared and analyzed by various design parameters (area of splice plates, stiffness of splice plates, and stiffness of bolts). The moment-displacement relations of structures for the various design parameters were investigated to analyze effects of each parameter in ultimate behavior of the structures. Also, the effects of each parameter were compared by force.

분포형 수문모형인 WEP(Water and Energy transfer Processes)는 일본토목연구소의 물순환 해석 모형으로써, 짧은 구동시간에도 불구하고 물과 열에너지의 순환을 파악하는 데 효과적인 것으로 알려져 있다, 그러나 모의에 필요한 자료입력 과정이 매우 복잡하고 불편할 뿐 아니라 획득된 결과를 효율적으로 표현하지 못한다는 약점을 가지고 있어 활용도가 높지 않았다, WEP 사용성 향상에 관한 요구가 높아짐에 따라, WEP 전 후처리 프로그램인 WEP+가 개발되었다. WEP+의 개발은 WEP 모형에 대한 방대한 양의 입력 자료를 효과적으로 구축하고, 다양한 기능을 통해 모의 결과에 대한 분석을 용이하게 할 수 있도록 하여 사용자가 직관적으로 모형을 적용할 수 있도록 하는데 그 목적을 두고 있다. WEP+는 기존 WEP의 복잡한 입력과정을 체계화 하여, 사용자가 쉽게 접근할 수 있도록 설계되었으며, 입력 자료의 편집기능을 도입하였다. 또한 복잡하게 연관된 매개변수들의 적합성 여부를 사전에 점검 할 수 있는 기능을 부여하여 모의 도중 오류가 발생하거나 잘못된 모의 결과를 생산할 가능성을 최소화 하고자 하였다. 모의 결과에 대해서는 하천 유출, 지표면 유출, 지하수 유출, 토양수분, 지하수위, 증발산 등 세부 수문요소에 대한 모의 결과를 지점별 시계열과 전체 유역에대한 분포형 자료로 확인할 수 있다. 본 연구에서는 새로 개발된 WEP+ 각 모듈의 기능과 인터페이스를 살펴보고 적용사례를 중심으로 결과분석과 활용방법에 대해 고찰해 보도록 한다.
