For the improvement of APR1400 Diverse Protection System (DPS) design, the Advanced DPS (ADPS) has recently been developed to enhance the fault tolerance capability of the system. Major fault masking features of the ADPS compared with the APR1400 DPS are the changes to the channel configuration and reactor trip actuation equipment. To minimize the fault occurrences within the ADPS, and to mitigate the consequences of common-cause failures (CCF) within the safety I&C systems, several fault avoidance design features have been applied in the ADPS. The fault avoidance design features include the changes to the system software classification, communication methods, equipment platform, MMI equipment, etc. In addition, the fault detection, location, containment, and recovery processes have been incorporated in the ADPS design. Therefore, it is expected that the ADPS can provide an enhanced fault tolerance capability against the possible faults within the system and its input/output equipment, and the CCF of safety systems.

Project Financing (PF) is the long-term financing of infrastructure and industrial projects based upon the projected cash flows of the project rather than the balance sheets of its sponsors. However, the financial institution, the subject of financing in the case of PF in Korea, the lack of validation system of business, rather than to assess the feasibility of the project, requested a credit reinforcement to the construction company, the fact is Construction Company on loans of the employer is the guarantor or debt argument commitments accordingly. As a result, PF contingent liabilities, which are indirect debt, are triggered in the construction company, not included in the financial statements, along with the disclosure standards established according to 2009 PF contingent liabilities, and major can be a management item. In this study, PF contingent liabilities is of Pearson of the index and the PF debt ratio showing the main financial ratios and risk by classifying the credit rating and contractors Ranking of construction companies in order to analyze the impact on the financial condition of the company was performed correlation analyzes, through the Pearson correlation coefficient analysis indicated quantitative or negative relationship to derive the explicit indication.

A submittal, as a part of three main project management processes: production control, submittals and change orders, is the transmission of information from the subcontractor to the general contractor to the owner, architect, and structural engineer, for review and approval. The purpose of the submittal process is for submittals to be approved in order to start construction. This benefits the contractor by ensuring that the finished project will meet the expectations of the owner. This paper analyzed a case study regarding the submittal process for the local-based environmental construction company, which typically works as a subcontractor and may hire other subcontractors for additional work when applicable. The aim of this study was to roughly evaluate a project management process and understand the submittal process through the study of a case involving the local company.

Data were collected by the interviews from the heads of management departments of housing construction companies. Twenty-one companies selected were divided into three groups according to the amount of housing supply. Major result were as follows : 1) departments of defect-repair in housing construction company are divided into sub-system according to the size of housing supply. 2) the judgement of the range and period of defect-repair are extracted. They are, according to the order of their importance, constructional defect, functional defect, aesthetical defect and the defect in use.

In this paper, a survey related to excavation construction activities among national and international construction companies was conducted to evaluate site productivity in construction industry. To analyze the respective productivity levels of each construction company, a benchmarking measures analysis that featured calculations of the performance ratio (PR) and performance management index (PMI) was performed. As a result of these analyses, it has been found that the work performed by local companies was marked by lower productivity and that of international companies was characterized by good productivity. Further analysis of construction workforce resources P% revealed that a construction company's productivity is largely dependent on production capacity and consumption resources, which means that the retention of skilled workers and utilization of high-quality resources yields the highest level of productivity. These results suggest that for a local construction company to be competitive in the construction work market, it must retrain skilled craftspeople, foremen, engineers, and project managers, and strengthen its building capability by leveraging new equipment and technologies.

Construction companies are fulfilled in according to project, and it is difficult to execute the standardized process in various construction projects. Thus many construction companies is adopting BPM(Business Process Management) that meet business process change and business improvement. However, it is difficult to apply BPM in a lump because of difference of BPM characteristics and company's strategies. For this reason, it is desirable to select business process based on company's priority. This study indicated need of method for selecting business process through studying current researches, and made BPA for construction company by analyzing business process in construction company. Moreover, this study indicated core business process from a point of profitability and growth view through grasping strategic goal priority. And also, it proposed criteria for process evaluation for BPM adoption, evaluated core business process, and indicated prior business process for BPM adoption.

The past IMF foreign exchange crisis and subprime financial crisis had a big influence on variability of macroeconomics, even if the origin of its occurrence might be different. This not only had a significant infrequence on the overall industries, but also produced many insolvent companies by being closely linked with a management environment of an individual construction company leading the construction industry. The purpose of this research is to investigate characteristics of management condition of construction company according to the size of construction company using KMV model developed on the basis of the Black & Scholes option pricing theory. This research has set 28 construction companies listed to KOSPI/KOSDAQ for applying the KMV model and measuring the level of the default risk of construction companies. The data was retrieved from TS2000 established by Korea Listed Companies Association (KLCA), Statistics Korea. The analysis period is between first quarter of 2004 and fourth quarter of 2010. This research examine characteristics of the level and fluctuation process of the management condition of construction company according to the size of construction company.

The old Samcheok construction company housing in Donghae City was built for employees of Nitrogenous lime factory with railway construction in 1939. The 31 company houses are arranged in a rows including a House A, two No. 2 and 3 Houses, a dormitory, 12 row houses of two households, and 15 row houses of four households. At present, they are preserved with prototype at that time of building as a private company. Researching the architectural characteristics from A and No. $2{\cdot}3$ detached houses of them, the results are as follows. The tea room, living room, and kitchen are centralized and connected with toilet, bathroom, and maid's room by corridor. The exterior wall was finished with paintwork on cement mortar on stud wall framing plastered. The key exterior elements such as diamond shaped asbestos slate, large openings, corner bay window, lintel cornice are in accordance with drawings that they were first designed. The wooden roof structure is based on the structure that supports transverse load with a beam and beam plate instead of thrust. The kitchen and toilet are remodelled and only seem to be a mere shadow of their former self, but the position of sink and toilet bowl is the same as before.
