Rising interest rates positively affect investment in construction, while falling interest rates affect it negatively. In other words, the interest rate is one of the most critical factors affecting the construction sector. The purpose of this research is to analyze the relationship between the annual interest rate and construction contracts, and to present a model for quantitatively forecasting the economic performance of the construction sector. Based on the statistical data of interest rate changes for 19 years (from 1991 to 2009), this research induces an equation through regression analysis that incorporates interest rate and construction contract amounts as independent and dependent variables, respectively. The result of the analysis shows that, in the building and private sector, the interest rates are closely related to, with a correlation coefficient as high as 0.85. It was also indicated that the contract amounts of private and building sectors may increase quite rapidly in 2012.

There are various factors to consider when parties to an international agreement draft a dispute resolution clause in their written contract. These factors can be classified into two categories. The first category is about the parties and the nature of the contract, such as the parties' places of business and whether the contract contains a simple transaction or has a complicated nature. The second category is about the applicable rules of the parties' places of business or performance such as the private international law, service of process rules, and enforcement of court judgment and arbitration award rules. When parties to an international contract agree to a litigation, they normally choose a forum court and a governing law. In selecting a forum court and a governing law, the parties must consider private international law, service of process rules, and enforcement of judgement rules of candidate forums. In case the parties agree to an arbitration, they have to choose between institutional arbitration and ad hoc arbitration. For ad hoc arbitration, parties still need to further agree on which arbitration rules to use, and in which place the arbitration shall take place. Mediation involves a similar kind of decision as with arbitration. Traditionally, national courts of the parties' places of business have been used as litigation forums in dispute resolution clauses but, recently, arbitration is being increasingly employed as an alternative dispute resolution method in international contracts. Moreover, there have been international efforts to utilize mediation as a dispute resolution method in international commercial issues. Rather than simply taking a dispute resolution clause provided in a sample written contract, parties to an international contract must carefully consider various relevant factors in order to insert a dispute resolution clause which will work well for a particular contract.

Blockchain technology is a system in which data from users participating in blockchain networks is distributed and stored. Bitcoin and Ethereum are attracting global attention, and the utilization of blockchain is expected to be endless. However, the need for blockchain data privacy protection is emerging in various financial, medical, and real estate sectors that process personal information due to the transparency of disclosing all data in the blockchain to network participants. Although studies using smart contracts, homomorphic encryption, and cryptographic key methods have been mainly conducted to protect existing blockchain data privacy, this paper proposes data privacy using matrix character relocation techniques differentiated from existing papers. The approach proposed in this paper consists largely of two methods: how to relocate the original data to matrix characters, how to return the deployed data to the original. Through qualitative experiments, we evaluate the safety of the approach proposed in this paper, and demonstrate that matrix character relocation will be sufficiently applicable in private blockchain environments by measuring the time it takes to revert applied data to original data.

Investment authorities are broad financial institutions that carefully manage investments on behalf of the national government using a long-term value development approach. To provide a stronger structure or framework for In-vestment Authorities to govern the distribution of funds to public and private markets, we've started research to create a blockchain-based prototype for managing and tracking numerous finances of such authorities. We have taken the case study of Oman Investment Authority (OIA) of Sultanate of Oman. Oman's wealth is held in OIA. It is an organization that oversees and utilizes the additional capital generated by oil and gas profits in public and private markets. Unlike other Omani funds, this one focus primarily on assets outside the Sultanate. The operation of the OIA entails a huge number of transactions, necessitating a high level of transparency and administration among the parties involved. Currently, OIA relies on various manuals to achieve its goals, such as the Authorities and Responsibilities manual, the In-vestment Manual, and the Code of Business Conduct, among others. In this paper, we propose a Blockchain based framework to manage the operations of OIA. Blockchain is a part of the Fourth Industrial Revolution, and it is re-shaping every industry. The main components of every blockchain are assets and participants. The funds are the major assets in the proposed study, and the participants are the various fund shareholders/recipients. The block-chain's transactions are all safe, secure, and immutable, and it's part of a trustless network. The transactions are simple to follow and verify. By replacing intermediary firms with smart contracts, blockchain-based solutions eliminate any middlemen in the fund allocation process.

With the number of social overhead capital(SOC) projects that introduce private capital on the rise, overseas construction global companies today need to establish and advance their overseas order strategies. In this context, the purpose of this study is to develop the public private partnership(PPP) capacity evaluation model for developing countries and use it for domestic overseas construction companies to establish strategies for overseas expansion. The PPP competency evaluation model analyzes the importance of PPP competency evaluation items and infrastructure environment competency evaluation items through a review of previous studies and an interview survey with overseas construction experts. Through the above analysis results and expert surveys, problems that may occur when overseas construction companies enter the PPP market were derived, and improvement measures were proposed. Countries with a high probability of overseas construction companies entering the PPP market were determined to be those that have a mature PPP system, low risk in construction, and a good entry environment with a high infrastructure market size and growth rate. In addition, a lack of PPP investment experience, the absence of information on the infrastructure environment, and a shortage of PPP experts were identified as problems when entering the overseas construction PPP market. As an improvement measure, it was suggested to enter in cooperation with domestic and foreign companies. In addition, a plan was proposed to develop a curriculum to secure experts in areas such as PPP finance and contracts and to provide PPP information for each country. These findings are expected to contribute to overseas construction companies proposing strategies for entering the overseas construction market and using them for overseas expansion strategies and policy establishment.

This study is to introduce the Chinese Contract Law against non-performance of the contract and to solve the wide range of problems involving to executing the trading contract. The parties' liability for the period of performance, the place of performance, the failure to deliver conforming goods together with it's nature of the lack of conformity, and the methods of compensation against damages and the force majeure clauses application. Those issues affect directly to commercial transactions in international business. The focus is more on the interrelationship of private individuals in its trade and on aiming to remove the legal obstacles from the Chinese Contract Law to freely flow of international trade. Reference may include foreign corrupt practices, Conventions on Contracts for the International Sale of Goods and Laws of England, France, and Japan. This study has brought the efforts of these issues in the full spectrum of performance and with concentrations on effectiveness to avoid the different viewpoints of the general principles of CISG and commercial practice founded pre-eminently. This study, in presenting the legal framework, will contribute to a better understanding of the purpose of rules of Chinese Contract -Law as they interact to the benefit of the parties involved in international trade transactions. The writer believes that a problem-oriented approach and the concentration as outlined above would offer a different perspective for law faculty teaching in this area and hope that this study can be sufficiently diverse to satisfy many of those views.

While universities are making every effort to improve the housing welfare of university students by establishing new dormitories, the construction of school dormitories has intensified the conflict with other certified real estate businesses on the basis of their right to survival. Thus, it is necessary to analyze the causality in the conflict to coherently understand the conflict between these stakeholders. To do so, this study conducted a survey questionnaire on certified real estate businesses in the vicinity of private universities with dormitories in the metropolitan area. This study targeted licensed real estate brokerage agencies that conclude rental contracts in view of different stances, and control the real estate rental market by controling their conflict. Investigated the influence relationship between universities and licensed real estate brokerage agencies in relation to construction of private university dormitories and the effect of this conflict on management performance of licensed real estate brokerage agencies, and analyzed the relationship among relevant variables to see if their dormitory recognitions have a moderating effect. In addition to analyzing the causality of conflict level (perceived conflict, expressed conflict), conflict management, conflict outcome, and management performance, the study also verified the moderating effect of perception on dormitory and the mediating effect of conflict management. The results showed that conflict level had a negative (-) effect on conflict management, while the perceived conflict and conflict management of the conflict level had a negative (-) effect on the conflict outcome. In the relationship between perceived conflict and conflict outcome, conflict management had a complete mediating effect while expressed conflict had a partial mediating effect. Lastly, the perception of university dormitories did not have a moderating effect for the influence of conflict management on conflict outcome.
