Change orders have been widespread in both the private and public construction sectors. In particular, in the case of G2B (Government to Business) contracts, adjustment of contract price and/or schedule extension is a frequent occurrence due to change orders. To uncover the causes of change orders and suggest an appropriate strategy, this study analyzed 296 cases of change orders in military facility construction projects from 2008 to 2010. The analysis revealed that the major causes of change orders are users' additional requirements (28.38%), a change of finishing materials (23.99%), and change of footing type (17.57%), in that order. Building on the results of this analysis, the authors suggest plans for practical improvements. Specific recommendations include 1) reflect user requirements at the early stage, 2) minimize the use of additional budget due to change orders, and 3) reduce the process and time for contract amendment, among others. The results of this study may provide significant implications to those involved in military construction projects, particularly project owners (i.e., the Ministry of Defense) and contractors.

본 논문은 날씨파생상품이 전기도매시장에서의 가격 및 수량 위험의 헤지수단으로서 활용될 수 있다는 것을 보여주고 있다. 또한 일별 수준의 가격과 물량이 아니라 여름기간 동안의 전기도매시장에서의 전기구입 비용 혹은 전기판매 수입을 대상으로 하여 날씨관련 계약형태의 위험헤지효과를 살펴보았다. 날씨관련 계약들이 전기도매시장의 시장신호를 더 잘 보전하고 있으며, 도매전기 구입관련 금융위험을 더 잘 헤지함을 발견하였다. 전기도매시장에서 선물계약과 날씨파생상품을 결합하였을 경우, 더운 날의 경우 높은 전기생산비용이 가격에 반영되며, 전기판매 수입 혹은 전기구입 비용의 변동성이 현저히 낮아진다는 것을 발견하였다.

The purpose of this paper is to review the empirical study results of conversion factors(unit prices) for relative values of health care services in the national health insurance system and establish optimal classification of health care institutions for feasible contract of conversion factors between National Health Insurance Corporation(NHIC) and provider groups, based on legal backgrounds and types of health care service delivery system. some empirical research evidences shows the validity of applying multiple conversion factors to annual contract for reimbursement in the national health insurance. Policy recommendations suggest that clinic, hospital, general hospital, tertiary hospital, dental clinic, oriental medical clinic, pharmacy, and public health centers would be a basic category of provider groups for a meaningful price contract between the NHIC and providers.

This paper proposes a pricing model for IPOs which can reconcile the average underpricing phenomenon with the expected wealth maximizing behaviors of market participants. Under the usual informational asymmetry, the optimal offer price for best efforts IPOs is derived as a function of the uncertainty about market's valuation, the expected return on proposed projects and the size of offerings relative to the firm's market value. Depending on these firm-specific characteristics, best efforts IPOs can be underpriced, fairly priced, or overpriced. Introducing the investment banker as an outside information producer, the model is extended to provide empirical implications for pricing and underwriting contract choice decisions which are consistent with the existing empirical evidences. The model predicts that the issuers with greater uncertainty about market's valuation choose best efforts contract over firm commitment contract and the dispersion of initial returns would be greater for best efforts IPOs than for firm commitment IPOs.

Turnkey contract system is an effective ordering system for the ordering organizations that technical engineers are insufficient for their construction projects. It is possible to reduce project duration and to improve project quality in an integrated contract system between design and construction. However, owners can have a difficulty caused from unitary responsibility system. This study analyzes present situation and problems of turnkey contract system including railway projects. The result includes various methods for improving the system based on the analysis of bid price and selection procedure.

There is a growing trend for asset intensive industries to outsource maintenance services of their complex assets since outsourcing through service contract reduces upfront investments in infrastructure, expertise and specialised maintenance facilities. Estimation of costs for such contracts is complex and it is important to the user and the service providers for economic variability. The service provider's profit is influenced by many factors such as the terms of the contract, reliability of asset, and the servicing strategies, costs of resources needed to carryout maintenance. There is a need to develop mathematical models for understanding future costs to build it into the contract price. Three policies for service contracts are proposed in this paper considering the concepts of outsourcing maintenance service of assets to the service providers. Conceptual models are developed for estimating servicing costs of outsourcing through service contracts by considering time dependent failure mode.

Change is inevitable and is a reality of construction projects. Most construction contracts include change clauses and allowing contractors an equitable adjustment to the contract price and duration caused by change. However, the actions of a contractor can cause a loss of productivity and furthermore can result in disruption of the whole project because of a cumulative or ripple effect. Because of its complicated nature, it becomes a complex issue to determine the cumulative impact (ripple effect) caused by single or multiple change orders. Furthermore, owners and contractors do not always agree on the adjusted contract price for the cumulative Impact of the changes. A number of studies have attempted to quantify the impact of change orders on project costs and schedule. Many of these attempted to develop regression models to quantify the loss. However, regression analysis has shortcomings in dealing with many qualitative or noisy input data. This study develops ANN models to classify and quantify the labor productivity losses that are caused by the cumulative impact of change orders. The results skew that ANN models give significantly improved performance compared to traditional statistical models.

This case study surveyed management situations of environmentally friendly farming(EFF) producers' organization and their main activities. Farmers are aging as an average age of 55-year old and producing fruit-bearing vegetables. The EFF did not increase farmer's income, however, price and income was stabilized more than that of conventional farming because of contract farming. Farm household liabilities are caused by purchasing agricultural machinery, materials and so on. Farmers of EFF have been also cultivating conventional farming, but they don't plan much conversion intention of conventional farming into EFF owing to lack of differentiated and stable market for their EFF products. And they are guessing that EFF income will increase a little. For increasing of EFF income, they think that it is necessary to reduce production cost, produce high quality production, develop processing foods, enlarge contract farming and so on.

This study analyzed the recent precedents of the Korean Supreme Court's Royalty and License fee on this issue and presented implications for future taxation of Royalty and License fee and digital content imports related to reproduction rights. If the price related to imported goods and the price not related to them are combined, it is necessary to revise the statutes to supplement the allocation method of royalty and license fee. In addition, if there is an agreement or a back contract for intellectual property rights through the headquarters or branch office other than the trading party, a method of inducing the importer to voluntarily report it when reporting imports should be considered. Whether Royalty and License fee is taxed or not must be determined after examining the various contract details and circumstances of the transaction.

2008년 세계 금융위기를 계기로 국내 주택시장의 가격정체와 전세가격의 상승이 오랫동안 지속되고 있다. 전세가격의 지속적인 가격 상승은 대부분 사회초년생 및 무주택자가 선호하는 거주지인 전세주택에 있어 가격 상승으로 인하여 이들의 직접적인 거주 위협이 된다는 점에서 사회적 문제로 대두되고 있다. 정부는 다양한 정책을 통하여 이러한 전세가격의 안정과 무주택자의 거주지 안정을 위해 노력하고 있지만, 주택시장과 전세시장내의 구조적 이해관계에 대한 인식 부족으로 정책의 효과를 제대로 보지 못하고 있다. 이에 본 연구는 주택시장을 포함한 전세시장의 작동원리를 시스템 다이내믹스를 통하여 분석하고, 이를 바탕으로 정부의 전 월세 정책을 분석하였다. 분석결과 정부의 전월세 대책은 전세시장이 주택시장과 연결되어있다는 시각이 부족하고, 전세보증금의 지원이나, 임대인 세제지원 등의 단기적 미봉책 위주로서, 주택시장의 수요 공급 안정화를 전제로 하는 전세시장 공급 확대에 큰 영향을 미치지 못한다.
