Modular construction projects offer advantageous over conventional construction projects in the area of quality control through factory production. However, as clear standards and definitions for quality control activities have yet to be not established, it is difficult to judge the appropriateness of the scale of quality control costs, and it is also difficult to classify quality control activities by process stage. Therefore, in this study, a method for classifying quality management activities based on activity standards was presented, in addition to a method for classifying quality costs according to the PAF standards to check how effective the costs and activities are for quality control in the future. The findings of this study can be used to define the quality management activities for each stage of the modular construction project in the future, and to develop a database of evidence to determine the appropriateness of cost distribution accordingly.

특별관리임산물의 관리·감독을 위하여 법률을 바탕으로 품질관리제도를 마련하고 있으며, 현재 문서를 통해 관리하고 제도적인 신뢰에 의존하는 방식에 머물러 있다. 이는 많은 비용을 발생시키며, 제도를 악용하는 사기 사례가 발생하고 있다. 본 연구에서는 문제점을 해결하기 위해 블록체인을 이용한 특별관리임산물 품질관리 시스템을 제안한다. 해당 시스템은 품질 관리를 위한 문서를 법률에 따른 양식에 따라 전자문서로 생성하고, 문서 정보를 분산장부에 저장하여 누구나 확인 할 수 있도록 한다. 전자 문서들은 기관의 데이터베이스에 보관하여 확인 할 수 있도록 하며, 분산장부의 문서 정보 등록 이력을 통해 품질관리 이력을 추적하고 검증할 수 있도록 한다.

International financial crises of the mid-l990s are widely perceived as the trigger that prompted recognition of the need for a new data quality management by the OECD, IMF, Eurostat and individual statistical agency. The official statistics improvements schedule in Korea was launched in 1996 as part of a broader internationally-agreed-upon initiative to strengthen transparency and promote good governance practices. These new initiatives are based on the Total Quality Management(TQM) movement and other management frameworks broadening the concept of quality beyond the traditional statistician's concepts of data quality. This paper aims to evaluate the statistics quality of Land Price Index. Evauation Method is the National Statistical Office's Data Quality Management System which focus on accuracy, timeliness, relevance, accessibility, comparability, serviceability, efficiency.

In Korea, National spatial data infrastructure has implemented in order to integrated manage and share the national spatial information producted by public agencies and local governments. The necessities of systematic quality management are raised, because information, which is generated by different agencies, is integrative managed by national level. In this paper, the establishment of BPR(Business Process Reengineering) for national spatial data infrastructure quality management system. Quality management business is defined as quality management object definition, quality measuring, evaluation and analysis, and quality enhancement process. Next, activities for each process are designed. For the quality management business, business rule(BR) is required for determining error. We derive the BR for six objects(legal-dong, railway boundary, railway centerline, road boundary, road centerline, building) among the basic spatial information. Other information's BR can be generated by using the derivation method described in this paper. Based on the BPR of this paper and derived BR, national spatial data infrastructure quality management system can be implemented in the future.

Reviewing the previous researches related to SW quality, we find that they are mostly quality evaluation models for SW quality improvement and maturity-design models for software project management evaluation. There are few studies for the appropriateness of SW quality management by Quality Control(QC) functions. Moreover, they are bound for government's SW R&D projects in the view of the third party. Therefore, we propose means for the objective evaluation of SW quality management's appropriateness by QC functions. For this reason, there are three research proposes in our study as follows. Firstly, we produce problems for the evaluation of the existing government's SW R&D project management's appropriateness. Secondly, to overcome the drawbacks for the evaluation of the appropriateness of SW quality management, new appropriateness evaluation methods are proposed. Lastly, we investigate the availability and effectiveness of the appropriateness evaluation methods for WBS projects.

VoIP transmits voices over IP-based networks and it is the abbreviation of Voice over Internet Protocol. Recently, VoIP provides various services in addition to voices. Since VoIP services' provision is extending, VoIP service quality management is becoming an important issue. Therefore, in this paper, we study VoIP service quality management. We examine VoIP technology, service types, and network architecture. Then, we investigate key quality indicators(KQIs)/key performance indicators(KPIs) in terms of customers, not network service providers. Toward this, we also study the concept of general service quality management as well as the concept of telecommunication related service quality management. Moreover, we apply $\bar{x}$ and R charts to show how to use statistical quality control techniques in real telecommunication companies with one KQI.

Currently, Building Information Modeling (BIM) is an emerging technological shift that involves applying and maintaining an integral digital representation of all building information for different phases of the project life-cycle. Although BIM has been recognized as a main stream in the construction industry, it is difficult to ensure the quality of BIM data due to the problems such as internal errors of BIM tools and lack of guidelines considering design quality. Such problems give lots of difficulties to BIM adoption for designers, constructors, and owners. Therefore, it is necessary to develop the requirements including the object-oriented modeling method and property definition by applying the Industry Foundation Classes (IFC) which is an ISO/PAS 16739 standard for ensuring the quality of BIM data. This research aims at proposing the requirements considering the quality of BIM data and demonstrating the efficiency of the requirements with using the Solibri Model Checker (SMC) which is a quality control tool in a case study.

Owing to the growth of Information Technology, some of big general contractors have been interested in the development of Quality Management Information Systems to integrate the information of quality in planning, design, procurement, construction, and maintenance phases, and tried to maximize the usefulness of it. But the trend has confined only to some big general contractors. The purpose of this paper is to put together and analyze the character of Quality Management Information Systems of big general construction companies and classfy them into a result-focused system and a process-focused system in order to provide primary information for both of development and adoption of the systems.
