In order to develop VirtuAlmighty system, CPDM (construction project data management) and CPLM (construction project lifecycle management) model must be settled beforehand. Because most of information systems based on 3D-Design have its own database and business process. So, our team will develop collaboration management architecture of construction process for Decision Support based on PLM (Project Life-cycle Management). This architecture with business processes and Database can be used in process develop, process monitoring with many stakeholders of project, process change management, and so on.

This study was mainly concerned providing a basic of data for the more reasonable home management. The purpose study was to investigate the relationship of husbands and wives self-actualization and degree of joint decision-making. For the purpose of this study 500 questionaire were distributed to the marital in seoul. The 412 data were analized by Frequency, Percentage, T-test, ANOVA, Scheffe-test. The major findings of this study were as follows: 1) Over one and half of husbands and wives are try to be self-actualized. 2) The tendency of the husbands and wives decision-making was joint decision-making. 3) The important influential variables on the husbands and wives self-actualization husbands were age, life-cycle, job employment motivation. And wives were life-cycle, education, income, job, employment motivation. 4) The important influential variables on the joint decision-making were age, number of child, life-cycle. 5) A marital joint decision-making level differs significantly, according to the degree of husbands and wives self-actualization. The higher level of husbands and wives self-actualization, the higher degree of marital joint decision-making. The result of this study implies that a marital joint-making necessary in order to carry on happy home management and the reasonable home administration.

전통적인 환경에서 데이터 생명주기는 데이터-정보-지식-지혜 전환과정으로 요약된다. 반면에 빅데이터 환경에서 데이터 생명주기는 데이터-통찰-실행 전환과정으로 요약된다. 이러한 전환과정의 차이점은 데이터 생명주기를 지원하는 데이터 자원 관리에도 변화를 요구한다. 본 논문에서는 전통적인 데이터 자원 관리와 비교하여 빅데이터 환경을 위한 데이터 자원 관리를 연구한다. 특히 빅데이터 자원관리를 위한 주요 구성요소를 제안한다.

Construction projects are vulnerable to diverse internal and external factors, requiring systematic and consistent performance management along the entire life cycle of a project. In particular, urban renewal projects have a range of performance measures, including policy reconciliation and permits, project development, project financing, design, construction, and occupancy and maintenance. This requires a program-level megaproject approach, which integrates each stage of a project as well as variety of stakeholders' interests in pursuing a project from different perspectives. However, previous research on performance management has focused especially on the limited scopes of factors, including cost, quality, and schedule at the project level or on financial factors at the firm level. Given the lack of current approaches, this study suggests an integrated and systematic performance management scheme to control urban renewal megaprojects at the broadened perspectives of the program level. To this end, this study adopts the balanced scorecard approach and elicits key performance indices associated with various project configurations. Finally, an algorithm is presented for quantitatively assessing the level of performances along whole life cycle of urban renewal megaprojects.

This research presents a collaborative supply chain management system for curtain walls using Radio Frequency IDentification (RFID) to track the product and information flow among participants in high-rise building construction projects. This resarch developed a process model and a strategy for effective utilization of RFID technology through the curtain wall life-cycle. Then an information management system was developed to support the supply chain management of curtain walls with incorporating RFID into curtain wall products flow throughout the life-cycle. The system has been tested for validation and verification in a real world project.

This paper introduces an approach to an ontology-based knowledge framework for product life cycle management (PLM). Participants in a product life cycle want to share comprehensive product knowledge without any ambiguity and heterogeneity. However, previous knowledge management approaches are limited in providing those aspects. Therefore, we suggest an ontology-based knowledge framework including knowledge maps, axioms and specific knowledge far domain. The bottom level, the axiom, specifies the semantics of concepts and relations of knowledge so that ambiguity of the semantics can be alleviated. The middle level is a product development knowledge map; it defines the concepts and the relations of the product domain common knowledge and guides engineers to process their engineering decisions. The middle level is then classified further into more detailed levels, such as generic product level, specific product level, product version level, and product item level for PLM. The top level is specialized knowledge fer a specific domain that gives the solution of a specific task or problem. It is classified into three knowledge types: expert knowledge, engineering function knowledge, and data-analysis-based knowledge. This proposed framework is based on ontology to accommodate a comprehensive range of unambiguous knowledge for PLM and is represented with first-order logic to maintain a uniform representation.

The purpose of this study is to establish family life cycle of farm and to analyze changes of economic conditions-income, consumption expenditures, savings, assets, and debts-in farm household according to the family life cycle. Income, consumption expenditures, savings, assets, and debts functions are also estimated by age of household head. The data of Farm Household Economy Survey which was conducted in 1983 by Ministry of Agriculture and Fisheries is used in this study. Among total data of 2000, 1603 are analyzed for mean, percentage, and regression using CRISP Program at Office of Rural Development. The results of study can be summarized as follows; 1) Eight stages of family life cycle of farm are established according to the growth of the first child. They are: Establishment stage, Child bearing and preschool stage, Elementary school stage, Middle and high school stage, College and vocational adjustment stage, Period of children's marriage, Re-adjustment stage, and isorganizing stage. 2) The economic conditions of farm household are significantly fluctuated by family life cycle. Among the eight stages, stage Ⅱ is considered relatively comfortable living period and stage Ⅲ, Ⅳ are the most difficult periods of farm household economy. 3) The estimated functions of income, consumption expenditures, savings, assets, and debts by age of household head are as follows; Y(income) = 2, 354, 832+98,456T-1,036T2(F=11.746) C(consumption expenditures) = 81,876+154,976T-1,552T2 (F=37.272) S(savings) = 2,272,956+56,511T+516T2(F=4.262) D(debts) = 903,929+28,300T-438T2(F=3.339) A(assets) = 200,816+1,213,336T-12,930T2(F=21.069) To carry on a reasonable farm household management, a suitable measure to cope with the desire of family and the economic conditions of farm household should be prepared.
