Problem-Based Learning has many implications on teaching and learning. Through the problem-Based Learning, students device their plans to solve the given problems and discuss with workers to find and share some ideas or mathematical contents needed to solve those problems. In this paper we studied characteristics of Problem-Based Learning problem and tried o find out the standard criterion of problem analysis that were appropriate to Problem-Based Learning. We applied them to analyze problems in textbooks and problems that were developed for Problem-Based Learning. Using he result, the further research questions and implications were suggested.

PICC executes its role as a useful lex mercatoria in the continuously increasing international trade to be adopted as the standard criterion of prevention or dispute resolution. When considering the fact that GISG has not presented results beyond expectation in the past due to hard laws and legal deficiency, PICC, which possesses interpretation and supplementation function, is considered undoubtedly useful particularly in international commercial arbitration. As observed in the previously mentioned analysis on cases accumulated in UNILEX, PICC application and Arbitral tribunal in international contract between parties possess considerably large claim possibility and the number of actual application cases is continuously increasing. The fact that PICC has been composed as maximum common measures of continental and common law systems by traditional comparative legal scholars familiar with international trade can function as the fundamental principle in future global trade activity and can also act as the model law for uniting contract laws of nations. In this aspect, PICC can be evaluated to have considerably achieved enactment purpose of previous intention. However, additional topics that had not been accepted in the revised edition of PICC remain as assignments requiring solution, such as analysis and acceptance problem of comparative law, PR of PICC unfamiliar even to the relative parties of international trade and application in international contract, and absorption problem as model law in various domestic laws.

As the Fundamentals of Construction Business Act was revised in December 2004 and its implementing ordinances and enforcement regulations were adjusted in June 2005, the screening system of low price subcontracting has been an obligation to the public owners, having brought about arguments for and against since it enacted in 1983. The statutes for low price subcontracting have been reinforced from this year; for example, it underlines to submit to a project and builds an information network of subcontracting works. The system's original intention was that prevents shoddy and fraudulent constructions caused by low price subcontracting and precludes disturbances of fair trade by screening that whether it satisfies the conditions or not in advance. But, the criterion for the existing low price subcontracting has several issues having held up a true mirror to the real situation. It is arguable to discharge an important task with the primary purpose. This dissertation have researched the problem with a deposit of subcontract and the low price subcontracting basic rate are being used by the criteria for deciding whether it is a low price subcontracting or not, so showing the plan of reformation based on the findings, it wishes to contribute toward making the most of the system's essential intent.
