Jangan-sa is one of the Buddhist temples in the southeastern seaside district, which was restored directly after the termination of Japanese Invasion of Korea in 1592. Recently we could find out 4 records on the constructions of Daeoong - jeon in J angan-sa. These are written in the 12th year of Emperor Soonchi, written in the 8th year of Emperor Geonryung, written in 1947 Buddha Era and written in 1951 Buddha Era. Until the revelation of these records, the present building has been considered to be built in 1657, the 8th year of King Hyojong, based upon Kim Bang - han's "Jangan - sa Daeoong - jeon - gi". Because the gongpo of Daeoong - jeon was finished with the type of the late period of Chosun Dynasty, we doubt of the correction on it's building date, just in the year of 1657. Now we are able to examine the building date and the alteration date, based upon the actual measurement and constructional records of Daeoong - jeon. So to speak, the building destroyed in 1592, had been restored in 1658, the 9th year of King Hyojong and was reconstructed in 1744, the 20th year of King Youngjo. Afterward it was repaired on small scales in 1947 and in 1951. Though this building is considered to be lack of the completeness owing to the later alterations, it is still worthy heritage for the research on the building type at the directly after the termination of Japanese Invasion of Korea in 1592.

Result from Amendment of Apartment Houses Decree Customer Service, Recently, the starting point of Defects Liability changed "Criteria of Completion date" to "Delivery date to Divided property". Through the Law amended, There are some inconsistency between "Claim for repairing defects" and "Period of security deposit for repairing defects claim". If someone bought a house after Completion date, Purchasing period of "Claim to security deposit for repairing defects" lapsed without renewal. This research is to identify problems and solutions for improving the system.

We propose a robust event date model to estimate the date of a target event by a combination of individual dates obtained from archaeological artifacts assumed to be contemporaneous. These dates are affected by errors of different types: laboratory and calibration curve errors, irreducible errors related to contaminations, and taphonomic disturbances, hence the possible presence of outliers. Modeling based on a hierarchical Bayesian statistical approach provides a simple way to automatically penalize outlying data without having to remove them from the dataset. Prior information on individual irreducible errors is introduced using a uniform shrinkage density with minimal assumptions about Bayesian parameters. We show that the event date model is more robust than models implemented in BCal or OxCal, although it generally yields less precise credibility intervals. The model is extended in the case of stratigraphic sequences that involve several events with temporal order constraints (relative dating), or with duration, hiatus constraints. Calculations are based on Markov chain Monte Carlo (MCMC) numerical techniques and can be performed using ChronoModel software which is freeware, open source and cross-platform. Features of the software are presented in Vibet et al. (ChronoModel v1.5 user's manual, 2016). We finally compare our prior on event dates implemented in the ChronoModel with the prior in BCal and OxCal which involves supplementary parameters defined as boundaries to phases or sequences.

Currently, it is increasing the importance of floor impact sound performance in apartment building due to users' various needs for comfortable residential environments. However, there are little date on floor impact sound performance because Korean apartment building floor is an ON-DOL which is made of several elements. In this study, floor impact sound performance according to variation of floor construction method were investigated. And based on these investigated results, datas can be used to supply constructor and comsumer basis data to estimate floor impact sound performance.

Construction companies are now trying a variety of cost-cutting strategies in the midst of recent slump of construction market. Notably, contract workers and local hires are accounting for increasing portion of management manpower as a part of their cost-reduction drive. However, construction site manpower researches to date have focused primarily on productivity analysis of site laborers, with little attention to the productivity of site management resources. This study aims to analyze the staffing status of office building construction site management manpower in reference to project size. Conclusions herein will provide basic inputs for subsequent attempts to build a model to enable efficient staffing of construction site management manpower.

The purpose of this study is to establish a system that manages the safety of buildings efficiently by finding the correlation of elements related to the safety of buildings and intuitively visualizing them. Data were collected using the data of small-scale buildings managed by public institutions and the government, and an effective analysis visualization environment was established through pre-processing. We selected safety-vulnerable factors such as the structure of the building and completion date to find the relationship, and established a model to prioritize management to find vulnerable buildings.

Estimating the construction period at the initial stage of the project and determining whether it is appropriate is very important for the developer's decision-making and the success of the construction company's business. Existing researchers have conducted various studies to calculate the appropriate construction period, but there is no study on the influencing factors and methodology for the construction period of beam-column PC apartment building frame construction. The purpose of this study is to calculate the PC member assembly time using the mathematical algorithm of PC member assembly. The results of this study can be used as basic data to calculate the construction date of the standard floor of PC construction.

Busan's Haeundae Resort project, which is currently being constructed by POSCO E&C, comprises the 101-story Landmark Tower and two 85-story residential towers. Presently, foundation and basement construction is complete, with a final completion date set for 2019. Considerations about the construction and design of the three reinforced concrete high-rise buildings will be discussed in this paper.

The examples of developing a building site after the Woongjin period are mainly found in temple sites, tile-roofed building sites of unidentified features, and palace remains including the pavilion site with the river in the front(임류각지) inside the Castle of Gongsan, Gongjoo. In case of the Hanseong period, a glimpase of the features has gained in Poongnab mud castle and Mongchon mud castle, but the excavated relics are not yet enough to make some date out of them. After the Woongjin period of Baejae, the earth-ramming development method was used mostly to construct a building site, which is divided into horizontal and slant raising of the ground level. Both are used simultaneously, but there are the significant differences in the way of raising the ground level between them. Particularly, in case of the Wanggoong-ri relics in Iksan, the ground level was raised in a narrow line slantly, which is differentiated from other slant raising of the ground level, and its time of construction also is after that of others. In addition, the board-building development method used for narrow space is usually found in the remains since the seventh century. However, there are not enough the relics of Baekjae to reveal the whole aspect of building site development. It should be studied later through the subsequent excavation and research.
