Estimations of paddy field area are important for agricultural water supply planning. Especially these estimations have to be excused by drainage basin. In this research, we developed a paddy field estimation model considering shift-share effects such as national growing, structural, local effects. National growing effects are estimated by adopting the result of KREI-ASMO model which predict farm land area in national level. Paddy field structural effects are estimated using statistical data about farmhouse numbers and cultivation areas. Local allocation effects are calculated by differences of estimations and real data. The results using data from 1998 to 2003 show that developed model estimates 2006 paddy field areas in each province in 5% error and is applicable to predict future change of paddy field.

In this paper, I investigate the impact of quality management activities on the public sector within the framework of Malcolm Baldrige (MB) national qualify model. The Structural Equation Modeling approach has been employed to investigate the cross influences among the seven MB categories. This empirical study shows that a number of statistical hypotheses are significant. The leadership category is the most important driver among the quality management activities. This, in turn, implies that the main source in quality management is to foster a solid qualify oriented leadership system. Categories such as Information Analysis, Strategic Planning, Human Resource Development and Management, and Process Management are significantly related to the Customer Satisfaction category. In addition, leadership, Information Analysis, and Customer Satisfaction categories ere significantly influential to Management Performance.

This study was initiated to develop a precast polymer concrete production method and to describe an criterion for the optimum thickness of precast polymer concrete by a series of experiment and structural analysis. Nine specimens with different thickness and steel bar reinforcement were prepared and tested and analyzed with respect to structural behaviors. Cracking moment was mostly affected by the thickness but steel reinforcement seemed not to have effect on the moment. Data of the study could be widely applied in designing and planning of production processes of many polymer concrete products of which all or some of components are composed with thin panels.

This study investigated structural changes of the Korea's agriculture and proposed the new direction of rural and agricultural policy in Korea after economic opening. The major results may be summarized as follows: Firstly, the study identified structural changes of the country's peasantry under the economic opening system. Korean agriculture has been deteriorated in population structure, arable land size, and income composition. Secondly, according to above analysis on these changes it suggested that the traditional rural communities were exposed to collapse and this unwanted disaster could result in serious adversities to the national economy. Thirdly, this study proposed preservation policies for small scale farming households and also administrative preparations of multi-dimensional approaches leading to successful rural and agricultural planning.

Company A's core competency is IT internet security services. The Web diagnosis team analyzes the vulnerability of customer's internet web servers and provides remedy reports. Traditionally, Company A management has utilized a simple table format report for resource planning. But these reports do not notify the timing of human resource commitment. So, upper management asked its team leader to organize a task team and design a visual dashboard for decision making with the help of outside professional. The Task team selected the web security diagnosis practice process as a pilot and designed a dashboard for performance evaluation. A structural design process was implemented during the heuristic working process. Some KPI (key performance indicators) for checking the productivity of internet web security vulnerability reporting are recommended with the calculation logics. This paper will contribute for security service management to plan and address KPI design policy, target process selection, and KPI calculation logics with actual sample data.

건설공사에서 토공사가 차지하는 비중은 타공종에 비하여 높다. 즉 건설공사의 생산성을 향상시키기 위하여 토공사를 중점적으로 관리하는 일은 매우 중요하다고 할 수 있다. 그러나 현재의 토공 시스템은 굴삭 조종자와 현장 계획 관리자의 경험적 지식에만 의지하여 토공 계획을 수립하고 있는 실정이며, 또한 노동 집약적 토공작업의 한계를 벗어나지 못하는 현실로 인하여 토공사를 관리함에 어려움이 있다. 이러한 당면 과제를 극복하고자 BIM 기반의 토공 시스템에 대하여 소개하고자 한다. 본 논문에서는 굴삭 장비와 연계하는 토공 계획과 운영 자동화 시스템에 대하여 주로 다루게 된다. 굴삭 작업 계획 생성 시스템, 장비 조종 인터페이스, 웹 기반 Project Management Information System(PMIS)이 개발되는 과정에서 적용된 BIM 요소기술에 대하여 살펴본다.

건설공사 프로젝트는 사전 기획 단계, 설계, 계약, 시공, 운영 및 유지관리 등 각 단계의 다양한 참여 주체에 의해 프로젝트가 진행되고 각 분야 간의 원활한 의사소통을 통한 협력 작업으로 일을 진행한다. 그러나 각 단계별 참여주체간의 협업이 어렵고 정보교류가 원활하지 못한 문제점들이 있다. 또한 건설공정은 현장여건의 변화와 불확실성으로 인해 예측이 어렵고, 보다 신뢰성이 있는 계획의 부재로 인하여 각종 세부 공정들 간의 간섭을 유발하고 계획된 일정을 준수하기 어려워 불필요한 비용의 낭비와 공사기간의 증가를 야기한다. 이러한 낭비요인을 최소화하고 건축 프로젝트를 진행하는데 있어서 효율성을 높이기 위해서는 시공계획 단계의 신뢰성을 높여야 한다. 따라서 시공전의 계획 단계에서부터 4D 시뮬레이션을 통하여 이러한 문제점들을 파악하고 개선하는 것이 중요하다. 본 연구에서는 BIM기반의 시뮬레이션 프로그램의 기능분석을 통하여 효율적인 적용과 발전과정을 알아보고자 한다.

In this paper, we introduce a new technique for automatic construction of steel frames in high-rise buildings. Basically, we combine advanced robotic technologies to building construction techniques. Four main topics will be developed such as: 1) Planning and synthesis of automatic construction system, 2) Development of construction factory system with climbing oil-pressured robot, 3) Core techniques for automatic assembly for steel frames, and 4) Intelligent resource management system. We expect that this new technique will increase the construction efficiency and will alleviate the manpower shortage problem in the aging society.

The Burj Dubai Project will be the tallest structure ever built by man; when completed the tower will be more than 700 meter tall and more than 160 floors. The early integration of aerodynamic shaping and wind engineering considerations played a major role in the architectural massing and design of this residential tower, where mitigating and taming the dynamic wind effects was one of the most important design criteria. This paper presents a brief overview of the structural system development and considerations of the tower and discusses the construction planning of the key structural components of the tower.
