  • In addressing the goal for sustainability in the construction industry, the very materials used for construction and the methods utilized to implement said materials must be analyzed. Specifically, some traditional residential construction materials consist of wood, steel, and concrete. Because these materials vary in their levels of sustainability, there is a need to develop and explore new or other materials that can be used for residential construction. The primary purpose of this paper is to provide a review of interlocking earthen masonry units (IEMU) as an alternative option for residential building construction. This is in an effort to explore the variables impacting their existing and potential applications as sustainable materials and a method for residential building construction. IEMU's are then examined under the triple bottom line (TBL) sustainability framework which includes analyzing the environmental, economic, and social sustainability of IEMU's. The findings of this review may lead to further progression in the development of a framework for evaluating U.S. stakeholder adoption of IEMU's and potential implementation in U.S. residential construction.

  • Purpose: This study is to analyze the purchasing process and distribution management requirements for teaching materials that have important meaning in the practical field of preschool education. Research design, data and methodology: A structured questionnaire was used to survey 103 childcare staffs regarding the purchasing process and distribution managements. The collected data underwent Likert's 5-point scale analysis and keyword grouping. Additionally, ANOVA was conducted to examine the distribution management demands based on demographic characteristics. Results: The purchasing of teaching materials involved more offline channels than online, and the purchase decisions were predominantly made by principals rather than teachers. Although the purchasing process is similar to that of general businesses, there are difficulties in purchasing due to the disorganized distribution channels and limited accessibility to product information. Additionally, the management of inventory for teaching materials is challenging due to limited personnel and storage. Childcare staffs have requirements for classification systems, evaluation criteria, environments and policies related to teaching materials distribution. The need to introduce a teaching material evaluation and certification system to ensure quality was not high. Conclusions: Most of the respondents recognized that strict management and measures should be taken for the distribution of teaching materials. There were differences in the demand of teaching material distribution depending on the respondents' status, age, education, and experience.

  • Construction projects, including housing, are carried out over long periods of time. According to changes to the construction period, the cost of input materials and wages also changes. Therefore appropriate management is important in order to minimize cost risks caused by fluctuations in prices. In Korea, housing units are usually sold in lots prior to construction completion. Therefore, careful management of input elements such as materials and equipment that are sensitive to price fluctuations is very important. This study deals with how the price fluctuation of materials, labor, and equipment influences the change of housing cost and seeks a way for cost management through identifying key resources sensitive to price fluctuation. As a result, a change to the housing cost index multiplies depending on cost changes of materials and labor together. Labor costs are a major factor on the housing cost index. In addition, certain types of materials and labor input to housing construction greatly influence price fluctuations. Thus, it is found that managing those main cost factors is the key for effective cost management.

  • Building materials have a great impact on the health of a building's occupants. Thus, it is imperative that their health-related properties be taken into during the course of construction project. Unfortunately, no current database system exists that can provide information on the health performance of building materials at each stage of construction project management, from planning and design to building and maintenance. therefore, an inordinate amount of time and effort is required to choose the right health-friendly materials(DBHM). To solve this problem, this study aims at building a database management system for health-friendly building materials. It analyzes the health-related properties and performance of various materials, and proposes a database structure and operation algorithm. The system proposed in this study is expected to contribute to the objective evaluation of health-friendly building materials through the accumulation of relevant data.

  • Trade can be greatly influenced by the change of international trade environment due to the characteristics of remote transactions. Furthermore, in the circumstance of emphasizing the national security again, the importance of the risk management of special materials has been increasing. As it was noted at Chapter 4, significant results such as the threat of enterprises' sustainable growth can be occurred when companies are related to the unlawful export of strategic materials or experience discouragement of export of main products. As the decision of strategic materials greatly depend on a specialized knowledge there is a possibility of misjudgement of strategic materials in terms of ordinary companies which is not accustomed to them. Furthermore risk management is more difficult due to the inclusion to the items of export license. To prepare such a risk of export of strategic materials, firstly, it should be checked to find whether counter traders are working in the industry which is not related to the spread of weapons of mass destruction, secondly, an appropriate process shall be designed and operated for products to be safely delivered to the trade counter. Therefore, our export enterprises have to introduce CP(Compliance Program), AEO or ISO28000 considering suitability for their actual situations not only to promote export and but also to avoid risk of export control and additional expenses. Through these appropriate processes, an efficient and effective management of the trade risk of strategic materials can be accomplished.

  • Indoor air quality has attracted great attention in recent years and thus the importance of managing finishing materials in terms of pollutant source control is being emphasized. Managing the finishing material at the design stage maximizes the efficiency of IAQ control at the following construction stage. However, there are insufficient investigations on the application of a specific finishing material management process, a database management system or a finishing material management process network. As a result, the main purposes of this study comprise comprehensive evaluation of IAQ performance from the selected finishing materials and auxiliary materials, application of the material management system basing on the types and characteristics of toxic substances generated from the indoor finishing materials, investigation of IAQ evaluation standard, and the overall IAQ evaluation method for the design parts. The result of this study will be the basic data to construct DBMS for management of finishing materials with respect to IAQ.

  • One of the important applications in Enterprise Resource Planning(ERP) systems is the Manufacturing Resource Planning(MRPII) system using Bill of Material(BOM). The manufacturing resource planning determines the quantity and timing of the production or purchase of subassemblies and raw materials needed to support the Master Production Scheduling(MPS). The bill of material is the recipe, a list of the materials needed to make a product. This paper intends to suggest a component-based materials management system using Unified Modeling Language(UML), as an application system for automobile part industry. Applying component based materials management systems designed with UML methodology, we analyzed the workflow and the document on materials management process from production planning to inventory management, and implemented a prototype of efficient materials management system, as a surrogate of existing material requirement planning(MRPI) system. To produce many other assemblies for a automobile part firm, component parts are assembled into subassemblies that are joined to assemble the finished product. Through the system suggested in this study, the level of inventory has cut down and the cost of inventory management has decreased. Also, the development method using UML makes the analysis and design phase to shorten in implementation period of MRPII system. The implementation of materials management system using CBD shows the ease of use in software reuse and the interoperability with corporate Internal information system. The result of applying object-oriented CBD technique is to minimize the risk of life cycle and facilitate the reuse of software as mentioned to limitation of information engineering methodology.

  • Libraries which have a large amount of genealogical materials need to manage them in a special way differing from the other materials. Although genealogy related materials have high pragmatic value, the reality is that the acquiring methods are limited to collect the genealogical table or is not systematic. Even the genealogical materials held in the library are not rationally organized. Under such circumstances, this study investigates the cases of the management of genealogical materials both in domestic and foreign institutions, and also examines the real situations of material organization such as the collection, the classification and the cataloging on the centering of the libraries which hold a large amount of genealogical materials. On the basis of this investigation, the study aims to measure the enhancement of the methods for collecting and organizing genealogical materials which enable the collection management and information retrieval fur them to be efficient and effective.
