Supervision work deals with important data necessary for the performance management on building construction sites in accordance with the Building Act. Therefore, this study attempts to use the data from supervisory reports to measure the performance of private building projects. Performance measurement is important for systematic management. However, there are only a few cases in which performance measurement is performed because it requires strenuous efforts to collect data for measurement. First, this study derived 6 performance areas and 15 indicators through a few rounds of expert group discussions. Then, we confirmed the performance indicators with high feasibility of data collection through a survey of supervision experts. It is expected that the data of supervisory reports can measure systematically performance and assist in speedy diagnosis of private building construction sites.

Social commerce (s-commerce) is a subset of e-commerce and uses social media for social interactions. Although s-commerce has been rapidly growing, disputes between some s-commerce firms and their consumers often occur over issues such as poor customer services, incorrect product information, and late refunds. In order for s-commerce to continuously grow, s-commerce firms need to build consumer-trust in their transaction process to minimize their consumers' uncertainty. The purpose of this study is to examine the relationships between the multidimensional trust (ability, integrity, benevolence) and the intention of continuous use of s-commerce. Moreover, this study presents antecedent factors needed for trust-building by applying the characteristics of s-commerce, and verifies the relations between the variables. We test and validate the research model and related hypotheses using structural equation modeling based on a survey done on 428 people who have previous experience with s-commerce. The result shows that trust has positive effect on the intention of continuous use, and verifies the necessity of the antecedent factors (social presence, assurance, informativeness, economic feasibility, and seller reputation) for trust-building. This study provides strategy for the continuous growth of s-commerce, and suggests theoretical implication that explains the relationship between the characteristics of s-commerce and consumers.

With the rapid development of digital technologies potential exists to expand upon the accessibility of fashion archives and increase their use as a pedagogical tool for research. At present this is compromised due the three-dimensional, tactile nature of the objects being viewed and the fact that they are not necessarily replicable in a digital format. The aim of this paper is to examine art and design students physical object research skills and discuss how they are positioned in relation to creative tools and strategies they use to produce outcomes such as they own collections and design responses. Findings and conclusions are drawn from projects concerned with the development and use of physical and virtual archives and inform the methodology used. Traditional methods and tools within higher education are discussed together with students increased use of digital resources and innovative ways to engage students. The academic challenge of supporting student engagement in archival research across digital and physical dimensions is explored. The papers findings indicate a need for further research considering the impact of digital technology on students' physical integration with archives and the need for more structured support surrounding student physical and digital research investigations.

The purpose of this study is to examine the physical characteristics of the detached housing area in the housing site development district. The process of this study is to investigate the characteristics of the physical structure and the building use, then to analyze the relationship of physical structure and the building use in the aspect of the morphological characteristics. The case study focuses on the Chil-kok2, An-Siml in Taegu. The streets pattern is composited gird and loop type mixed. The block is composited by 2 lots in general. But the obscurity of organization and character of the streets, the size and shape of lots which is not fit to the building use. A whole residential characters appears high residential density ratio. so residential environment became worse. The improving level of residential environment and efficiency of land use in the detached housing area of the housing site development district, firstly the propriety of the physical structure must be considered about detached house characters, and the housing uses which fit to the physical structure are needed, and also for the concrete realization of this, the designation of district, the zoning of residential area, the guideline of the district design, and establishment of comprehensive master planning in detached housing area are needed in aspect of the housing policy. As the result of this study, it suggests several design guideline to improve housing site development.

The commercial buildings are consuming about 30% of total energy used in Korea. And a large amount of energy consumption in commercial buildings is consumed by HVAC(Heating, Ventilation, Air Conditioning) system. Therefore, if we can reduce the energy consumption in HVAC or air-conditioning system in commercial buildings, the overall energy consumption in Korea can be reduced. Currently, an electricity charge called Time of Use (TOU) is applied to typical commercial buildings. This paper proposes the novel energy management method where the temperature setting of air-conditioning system are adjusted to minimize the use of electrical energy while indoor comfort level is retained. The simulation test for a typical commercial building shows that the proposed method gives over 10% savings in electricity bills and electricity consumption compared to the conventional air-conditioning method.

The continuous development of science and technology since the Industrial Revolution and the development of human civilization are based on the use of fossil fuels. However, the use of fossil fuels is increasing the greenhouse gas, the main cause of global warming, and global warming is an extreme climate anomaly that is rapidly increasing human and material damage. Therefore, efforts are being made worldwide to return greenhouse gases to pre-industrial levels. In Korea, 2050 carbon neutrality has been set as a major policy and efforts are being made to curb carbon emissions in the overall industry. Carbon emission suppression is based on the minimization of fossil fuel use, and research and development are underway on building a zero-emission house that minimizes the energy used in buildings in the construction field. Therefore, in this study, as part of the zero-emissions water system construction, waste resources generated at industrial sites were utilized and an integrated lightweight concrete solar panel grafted with a concrete lightweight panel and solar panel was manufactured and the possibility of its use was evaluated.

The purpose of this study is to suggest the way of analyzing land uses to utilize GIS in the field of urban planning. The Saga Land Information System was built in early 1990s. The building data were inputted by house investigation map(1/1,000) using digitizer. And urban planning basis investigation data in 1994 were utilized as the attribute data. Also, by calculating specialization factor, we distinct the characteristic of every land use of the city, and it compares every land use zone. This study calculated and compared an observation frequency and an expectation frequency of every building use and land use zone. We found that the use of the building tend to be controlled and guided by the land use zone.

As the city grows in population and size, land-use plan increasingly becomes a crucial element in developing a city-wide plan. In the process of developing the land use plan, identifying the present conditions and predicting the future conditions are the most important steps. That is, to understand the phenomena of land-use activities as well as to manage uses of the land efficiently require the comprehensive land use information system. This study intends to construct the land use database utilizing the Cadastral Map and Registered Building Data and to examine and suggest the application areas of the database. The database was constructed with those of Busan Metropolitan City. Using the established data, it shows how to use the database to identify the present conditions in Busan.
