This study is to analyze the feasibility of a project to digitalize the originals of cadastral maps of North Korea, a total of 299,688 sheets archived in South Korea's National Archives. The cost-benefit analysis is limited on the digitalization of the original cadastral maps of lands, woods and fields, information analysis on land attributes and platform construction, and the benefit analyses are divided into divided territory ones, namely intrinsic value, heritage value, direct and indirect utility value, military and strategic value and the foundation for inter-Korean unification, and post-unification ones such as the confirmation of ownerships, control of social conflicts, reconnection of family lines, arrangement of lot numbers, cadastral management and urban planning. Such benefits are estimated through the double-bound dichotomous choice of the contingent valuation method (CVM). The scenarios show that benefit in the divided territory is expected to reach 586.8billion won in the current value. The amount was calculated from the payable amount (7,925won) multiplied by the whole number of households. The post-unification benefit is estimated at 324.3billion to 594.1billion won as the payable amount (8,023won) is multiplied by the whole number of households.

The quality control personnel of the construction work shall establish and execute the quality control plan or the quality test plan and check the qualification of the used materials according to the process, the management of the test and inspection equipment, the quality education, the own quality inspection and measures. Management and quality test of Korea and plays an important role in preventing accidents. However, related organizations did not explicitly disclose their roles in quality testing and quality control tasks while changing the names of quality control personnel to test personnel and quality managers when revising related laws and regulations and the application of labor costs. Therefore, a research of this is needed to improve conflicting situation. In this study, the ambiguous title relation to the quality control persons is improved to meet the requirements of the construction work based on related laws and regulations, and each role and title is classified as 'quality tester' and 'quality manager'. In other words, the person who carries out the quality test of the "Construction Quality Test Standard" specified in the Guideline for Quality Management of Construction Projects shall be the "Quality Tester" and the person who performs the quality control plan establishment and execution work specified in the Enforcement Rule of the Construction Technology Promotion Act shall be referred to as the 'Quality Manager'.

The embedded software has been become more important than the hardware in mobile systems in ubiquitous society. The improvement models such as CMMI(Capability Maturity Model Integration) and SPICE(Software Process Improvement and Capability dEtermination) are used to improve the quality of software in general systems. Software process improvement is also necessary for mobile embedded software development to improve its quality. It is not easy to apply the general software improvement model to the mobile embedded software development due to the high cost effectiveness and heavy process. On the other hand, XP has the characteristics on focused communications with customers and iteration development. It is specially suitable for mobile embedded software development as depending on customer's frequent requirement changes and hardware attributes. In this paper, we propose a framework for development small process improvement based XP(eXtreme Programming)'s practice in order to accomplish CMMI level 2 or 3 in mobile embedded software development at the small organizations. We design and implement the Mobile Embedded Software Process Improvement System(MESPIS) to support process improvement. We also suggest the evaluation method for the mobile embedded software development process improvement framework with CMMI coverage check by comparing other process improvement model. In the future, we need to apply this proposed framework to real project for practical effectiveness and the real cases quantitative. It also include the enhance the functionality of MESPIS.

Complexity metrics have been developed for the structured paradigm of software development are not suitable for use with the object-oriented(OO) paradigm, because they do not support key object-oriented concepts such as inheritance, polymorphism. message passing and encapsulation. There are many researches on OO software metrics such as program complexity or design metrics. But metrics measuring the complexity of classes at the OO analysis phase are needed because they provide earlier feedback to the development project. and earlier feedback means more effective developing and less costly maintenance. In this paper, we propose the new metrics to measure the complexity of analysis classes which draw out in the analysis based on RUP(Rational Unified Process). By the collaboration complexity, is denoted by CC, we mean the maximum number of the collaborations can be achieved with each of the collaborator and determine the potential complexity. And the interface complexity, is denoted by IC, shows the difficulty related to understand the interface of collaborators each other. We verify theoretically the suggested metrics for Weyuker's nine properties. Moreover, we show the computation results for analysis classes of the system which automatically respond to questions of the user using the text mining technique. As a result of the comparison of CC and CBO and WMC suggested by Chidamber and Kemerer, the class that have highly the proposed metric value maintain the high complexity at the design phase too. And the complexity can be represented by CC and IC more than CBO and WMC. We can expect that our metrics may provide us the earlier feedback and hence possible to predict the efforts, costs and time required to remainder processes. As a result, we expect to develop the cost-effective OO software by reviewing the complexity of analysis classes in the first stage of SDLC(Software Development Life Cycle).

While the socioeonomic status of Koreas has been dramatically increasing in recent years, chronic and geriatric diseases have also been on the rise, bringing about many changes in our health care system. The basic goals of the home health care are to reduce health care costs, to increase the attrition rate in general hospitals, and to care for patients effectively and conveniontly at home. The purpose of this paper is to review and examine the current status of the home health care in Korea throughout the reports, surveys, other informations and education system of home health nurse. We identified the various types of home health care services programs, such as hospital-based home health care operated in public sector(demonstration project) and community-based home health care in health centers or in private sector, that is, Korean Nurse Association. Hospital based home heatlh care model was established as an alternative to traditional in-patiet services. Quality assurance and client satisfaction is an important measure of care received and establishment of payment and reimbursement for home health care services is important in promotng the home health care. We found out a fee-per-visit system composed of three kinds of fees : a basic service fee(16,000 Won), a travel fee(5,000 Won), and per-service fees (variables). Like fees paid for in-patient care, insureds pay 20% and insurers pay 80% of the basic and per-service fee. The travel fee is borne totally by the insured. Home health care continues to be viewed as not only the most preferred way to provide care to clients, but also the most cost effective. Home health care is that component of a continuum of comprehensive health care whereby health services are provided to individuals and families in their places of residence for the purpose of promoting, maintaining, or restoring health, or of maximizing the level of independence, while minimizing illness. Services appropriate to the needs of the individual patient and family should be planned and provided, nursing is to be a force for positive change and enhanced the nursing professionalism. Whatever type of involvement of home health care, it is essential to remember that home health care is highly service-oriented and highly touch health car deilvery system.

Young Jong Grand Bridge is approach traffic road of New Inchon International Airport which covers hub airport function in northeast asia. The total span length of this bridge is $4,420{\cal}m$ and this main bridge type is, the first in the world, Double Deck Self Anchored Suspension Bridge, designed as double deck systems to be arranged by road and railroad. Approach bridges to be connected with main span also are composed double deck steel truss and steel box girder to consider a continuity with this span. Our company erected $1,375{\cal}m$(about 60,000tons) of double deck steel truss bridge type which is composed by 6 traffic lane on upper deck and 4 traffic lane and Double track railroad on lower deck. The original installation method of this bridge was planed to install about 75 meters bridge blocks to use floating crane, after temporary bent was constructed between permanent piers. But this method which had to construct many temporary bents in the sea had the matter that construction periods can become lengthen and construction cost can be risen. To overcome the uncertainty to ensure high qualify of bridge and economic project execution, our company developed new bridge erection method to assure both quality control and economic construction work. The new erection method which was developed by us was one that could transport and install long bridge block, $120{\cal}m$ unit at a time and that temporary bent was not required. We hope that this paper is used as technical data which will erect bridge in the western sea and others marine region.

The purpose of this study is to survey the community support program of Green Belt from 2001 to 2011 and propose the improvement of the institution. For research method, the projects were analyzed by year, area, and category using statistical data. The improvement of the institution was drawn through the opinion survey of the interest group such as residents and public servants. For 10 years, 2007 community support projects were carried out and the total amount of government expenditure was 583.9 billion won. Among the support items, life convenience projects comprise 96.7%. For area, metropolitan area comprise 32.5%. There is a bias in items and areas. According to the survey of the residents and public servants, the satisfaction for the community support program is increasing. But it is necessary to enlarge the direct life cost support, activate community involvement and develop new project type. Proposed new projects are such as making characteristic village for income creation, planning for the landscape preservation using historic and traditional resources, making leisure space for nearby residents, and projects for the aged people. And it is proposed to give incentive to the characteristic village projects through competition.

In 2012, Korean overseas construction market has achieved 64.9 billion dollars of contract order and its amount has increased since the mid 2000's. However, importance of qualitative growth based on profitability as well as quantitative growth is also emphasized. This study analyzed overseas plant project's subcontract process management which is closely related to cost management as one of the qualitative growth methods. In order to select major subcontract processes, extensive literature review and focus group interview(FGI) were implemented and then professionals with years of experience in the overseas plant projects were participated in the questionnaire survey. The collected data were analyzed by Benefit-Structure Analysis(BSA) model. The findings of this study include: (1) the seven and six subcontract processes are positioned in the area of importance control factor and in the area of maintenance/control factor, respectively; (2) administration capability attainment is needed for the six subcontract processes in the area of importance control factor and sustainable management system is required for the processes in the maintenance/control factor area. The further research will identify key subcontract processes to be managed for overseas plant projects by Korean EPC contractors based on the findings of this research.

Recently private procurement projects for urban infrastructure have been emphasized and introduced by government(both central and local) as an important method to supplement public budget shortage and to improve creativity and efficiency in its construction and operation, and hence to promote regional development. But these private procurement projects seem to be implemented under the neoliberal condition of urban policy for private capital to extend its sphere of investment and to ensure its opportunity of profit. Such private procurement projects for urban infrastructure have been legislated and widely applied since 1994 in S. Korea, but in recent years they have triggered out a variety of serious problems. In results of this study on the private procurement for construction and operation of Burnan Road in Daegu, it can be pointed out, it has led serious problems such as overestimation of traffic volume in plan, over-appropriation of construction cost and appurtenant business, irYational operation and account of the operating firm, problem in refinancing and change in contents of practical agreement, and over-compensation of minimum operation revenue. Some measures that can be considered as alternatives to resolve those problems and to operate more rationally the Buman Road include those of increasing traffic revenues, of reducing supports of public financing, and withdrawal of (part or whole of) operational right from the private firm.

Based upon XML, a standard document format on the web, there have been many active studies on e-Commerce, wireless communication, multimedia technology and so forth. JML is an XML application suitable for understanding and reusing the source code written using JAVA for various purposes. And it is a DTD which can effectively express various information related to hierarchical class structures, class/method relationships and so on. This paper describes a tool which generates JML document by extracting a comment information from Java source code and information helpful for reusing and understanding by JML in terms of the reverse engineering and a tool which generates a skeleton code of Java application program from the document information included in the automatically or manually generated JML document in terms of the forward engineering. By using the result of this study, the information useful and necessary for understanding, analyzing or maintaining the source code can be easily acquired and the document of XML format makes it easy for developers and team members to share and to modify the information among them. And also, the Java skeleton coed generated form JML documents is a reliable robust code, which helps for developing a complete source code and reduces the cost and time of a project.
