The Ministry of Land, Transport and Maritime Affairs has announced a policy which can enable the building of urban type housing with the use of a prefabrication method 2010. However, such may possibly be at standstill owing to the prefabrication methodology that has not been currently developed in Korea. Moreover, small households of consisting of one or two family members have been steadily increasing, but the small housing units in which they reside has been decreasing. Due to this situation, urban type housing has been proposed. To expand the propagation of such urban type housing and to promote prefabrication methods, the top priority project is to develop a technology that is able to reduce construction costs, as well as to shorten the actual construction period. In consideration of this prefabrication system for an avenue to solve such problems, a series of systems and policies for the fostering of prefabricated urban type housing has been proposed. This study is to review a series of methods, technologies and policies that are required for such urban type housing and henceforth, to utilize such as preliminary data for further prefabricated urban type housing.

Since Seoul city supplied 'Sangsang Children's Playground', domestic playgrounds are changing from formal facilities to creative play and learning space recently. From eco-friendly safe playground model development project, eco-friendly playground planning and its actual cases have been occasionally introduced. However, we could not know how well most playgrounds reflect eco-friendly features and whether they are eco-friendly or not because the definition about the concept of eco-friendly playground is inadequate and there are not the specific planning guidelines and evaluation standards for making the eco-friendly playground. Therefore, the development of guidelines for the construction of eco-friendly playground is required and evaluation guidelines for them should be made for the active dissemination of the actual eco-friendly playground and the proper construction of the eco-friendly playground. In this study, we defined the concept of eco-friendly outdoor playground and presented the types and characteristics of the playground based on the concept and suggested basic plan guidelines based on the existing requirements for becoming eco-friendly playground. For this purpose, we checked the plan's common points in the existing playground configuration requirements, installation standards, regulations, and safety standards, and offered the planning elements and guidelines through the analysis of outdoor space evaluation standard in eco-friendly safe playground guidelines and eco-friendly building certification system.

Extension IFC schema of subsidiary facilities were developed for the purpose of establishing an information model standard for roads. The IFC entities, types and properties for subsidiary facilities were defined through an analysis of the road design documents for the extraction physical component and design information. The converter and viewer for applying the new schema were then developed. Subsidiary facilities BIM models were converted to new IFC models to verify the research results. Standard BIM-based delivery and verification systems are enabled by using a standard model converted by new schema. Furthermore, it can establish an open BIM environment using an IFC over the entire life cycle of the civil engineering project.

Doosan Construction & Engineering Co., Ltd is building a railway tunnel beneath the Soo-Young River connecting MinLak Station and Centum City Station, a section 230, subway line 2, Pusan City, Korea. When completed the tunnel will have a finished inner diameter of 6.5m(21.311) throughout its total length of 840m(420m = 0.52 miles, Two Single Track Tunnel : 420m＋420m). The ground profile of the face toward shield machine is composed of multi layers, silty clay, clayey gravel, soft rock etc. This research paper is to predict ground deformation and variation of stresses around tunnel using Hyperbolic model, and to reflect the works on the next shield tunneling project. And this research paper is analyzed data of measuring instrument (such as settlement gauge, inclinometer, Multiple extensometer, etc.) which is installed along tunnel line for safety of tunnel. For calculations, the finite difference Method is applied. Backfill grouting material is supposed to have instantly strength of 10kg/$\textrm{cm}^2$ above, although its strength is available after 24 hours passed.

With a rapid expansion of the elderly population, there is a greater demand for the construction of senior complexes. However, due to a land price increase and insufficient financial resources, accommodating such a demand is challenging. Also, as aging progresses, many elderlies tend to be isolated from local community, because of deteriorating health. As a result, constructing senior complexes is becoming an important community project. The construction of senior complexes in Korea has been started since early 2000, so it is still in the beginning stage in Korea. However, in the case of Japan, they have more experience in building such buildings. Therefore, in this study, 49 senior complexes in Japan were analysed, and the following spatial characteristics were derived. 1. By classifying senior complexes largely into a complex type with similar facilities and a complex type with different facilities, 12 types were derived. Depending on the types of facilities, basic sharing rooms and selectively sharing rooms by need are suggested. 2. Depending on 4 characteristics, such as spatial composition, entrance type, circulation form, and complex facility type, 17 types of senior complexes were derived, and the characteristics of each type are presented.

Nine alkali-activated (AA) mortars were mixed and cured at water or air-dried conditions to explore the significance and limitation for the application of the combination of Ba and Ca ions as an alkali-activator. Ground granulated blast-furnace slag (GGBS) was used for source materials, and calcium hydroxide (Ca(OH)₂) and barium hydroxide (Ba(OH)₂) were employed as alkali activators. Test results clearly showed that the water curing condition was more effective than the air-dried curing condition for the formation of the denser calcium silicate hydrate (C-S-H) gels that had a higher molar Si/Ca ratio, resulting in a higher strength development. At the same time, the introduction of Ba(OH)₂ led to the formation of 2CaO·Al₂O₃·SiO₂·8H₂O (C₂ASH₈) hydrates with higher molar Si/Al and Ca/Al ratios. Based on the test results, it can be concluded that the developed cementless mortars have highly effective performance and high potential as an eco-friendly sustainable building material.

Large hospitals such as medical centers provide not only medical services, but also carry the responsibilities for emergency refuges, medical researches and education. The function of large hospitals is as important as other infrastructure systems such as highways, bridges, and utilities. When disasters occur, the hospitals have to provide emergency medical services for victims and support the patient's needs of health. In order to keep a smooth operation of hospitals, the maintenance management of hospital buildings should be carefully investigated. However, there are few researches focused on maintenance management issues of hospital buildings. This paper investigated the National Taiwan University Hospital (NTUH) and established a maintenance cost database. The NTUH is the best-known and most high-renowned medical center in Taiwan in which more than 4,000 employees serving approximately 2,000 in-patients and 7,000 out-patients daily. The data were collected from the NTUH which consisted of 16,228 maintenance records in the past ten years. This paper analyzed these data to obtain various characteristics of maintenance records, and revealed the key items of maintenance cost for large hospital buildings, which can provide the facility manager of hospital buildings to execute a proper maintenance policy for hospital buildings.
