Commercial transactions, one of the pillars of the capitalist economy, are occurring countless times every day, especially small and medium-sized businesses. However, small and medium-sized enterprises are bound to be the legal underdogs in contracts for commercial transactions and do not receive legal support for contracts for fair and legitimate commercial transactions. When subcontracting contracts are concluded among small and medium-sized enterprises, 58.2% of them do not apply standard contracts and sign contracts that have not undergone legal review. In order to support small and medium-sized enterprises' fair and legitimate contracts, small and medium-sized enterprises can be protected from legal threats if they can reduce the risk of signing contracts by analyzing various risks in the contract and analyzing and informing them of toxic clauses and omitted contracts in advance. We propose a risk prediction model for the machine reading-based legal contract to minimize legal damage to small and medium-sized business owners in the legal blind spots. We have established our own set of legal questions and answers based on the legal data disclosed for the purpose of building a model specialized in legal contracts. Quantitative verification was carried out through indicators such as EM and F1 Score by applying pine tuning and hostile learning to pre-learned machine reading models. The highest F1 score was 87.93, with an EM value of 72.41.

The renewable energy systems have been in the spotlight as an alternative for environmental issues. Therefore, the governmental policies are being implemented to spread of promote power generation system using renewable energy in various countries around the world. In addition, Korea has also developed a policy called the power trading contract which can profit from electricity produced from renewable power generation system through Korea Electric Power Corporation (KEPCO) and Korea Power Exchange (KPX). As a result, the power trading contracts can trade power after self-consuming in-house by using small-scale renewable power system for residential customers as well as electricity retailers. The power trading contracts applicable as a small-scale power system have a 'Net metering (NM)' and a 'Power Purchase Agreement (PPA)', and these two types of power trading contracts trade surplus power, but payment method of each power trading is different. The microgrid proposed in this paper is based on grid connected microgrid using Photovoltaic (PV) system and Energy Storage System (ESS), that supplied power to residential demand, we evaluate the operation cost of microgrid by power demand in each power trading contracts and propose the appropriate power trading contracts according to electricity demand.

With the exception of some large domestic airlines with adequate maintenance capability, most low-cost and small airlines do not have the facilities, equipment/tools, or manpower to perform periodic inspections over "C check." They are repaired according to maintenance programs specified by manufacturers. The outsourcing (domestic or overseas) of maintenance contracts is thus crucial to achieve good quality service at low cost, and these contracts therefore need to be signed with a full understanding of what is to be expected. This study aims to determine the requirements to be considered prior to finalizing such contracts.

In the 21st century knowledge and information society, Electronic Contracts made with the intention of electronic computer information networks are emerging as a new legal problem which can not be solved in the conventional legal system governing contracts. In other words, the indicator's decision determines the effect and formation of the contracts in the face-to-face or written contracts but electronic decision through computer information network is established the working process of electronic signals-electronic contracts are not only difficult to separate the decision-making process but questioned to be solved by the theory of the general legal action. Ministry of Transportation is scheduled to introduce real estate sales and lease contract using a variety of electronic devices such as computer, tablet PC, smart phones and so on without a paper contract. This system is conducted to global expansion of Seoul in demonstration zone on May 8, 2016 and will be implemented nationwide in the second half of 2017. Electronics contract Real estate has some benefits because made by linking electronic contract system and the electronic registration system - the economic effects discounts on various kinds of fees, the prevention from real estate fraud beforehand and the solution to the complexity of the process the seller and the buyer visits The Real estate agency. However, it has some problem- the disorder in the real estate contract market, the occurrence of the real estate agency accident and the author of the electronic real estate contracts have limited only to realtor. In this paper, I suggest the activation plan to search for establishment and effect of electronic contracts and declaration of intention in electronic depending on the Electronic Contract Real Estate system.

Judicial decisions make it clear that in all CIF, CFR and FOB contracts, incorporation of charter party into sale contracts is the only effective way for recovery of demurrage in the context of sale contracts. The case law would appear to clarify a number of important issues: The words of incorporation in the sale contract play a vital role in determining the extent of the influence of the charter party principles over the sale contract. Hence, unless it is expressly provided otherwise, the courts tend to apply the charter party principles to the incorporated charter party provisions to the extent that they make sense in the context of sale contract, and that they do not undermine the underlying foundations of international trade law. In this respect the courts also take into account the factual background of the case with a view to objectively ascertaining the intention of the parties. The law is, however, less clear on the effects of the incorporated charter party provisions in sale contracts. There is still no straightforward answer to the question of to what extent the charter party law is applied to the incorporated charter party provisions in the context of sale contracts. The case law on this matter merely provides piecemeal solutions, and it is not possible to extract a general rule which will help interpretation of those charter party provisions which have not yet been subject to litigation or arbitration. Therefore, it should be noted that the parties would prepare Incorporation Clause in their sale contracts in reliance of the rules to achieve the desired results.

The Governing Council of UNIDROIT at its 90th session adopted on 10 May 2011 the third edition of the Principles of International Commercial Contracts("UNIDROIT Principles 2010"). The UNIDROIT Principles of International Commercial Contracts first published in 1994 and in a second edition in 2004, are taken by legislators worldwide as a model for contract law reform and increasingly used in international contracting and arbitration practice, as well as by the courts to interpret and supplement the applicable domestic law. The UNIDROIT Principles are particularly useful to parties when negotiating and drafting international contracts. The new edition of the Principles, UNIDROIT Principles 2010, prepared by a group of experts from all over the world including representatives of numerous international organizations and arbitration centers. The UNIDROIT Principles 2010 contain new provisions on restitution in case of failed contracts, illegality, conditions, and plurality of obligors and obligees, while with respect to the text of the 2004 edition the only significant changes made relate to the Comments to Article 1.4.

Smart contracts are implemented by blockchain technology, which stores the terms of the contracts of both parties on the blockchain. In the event of an international dispute over smart contracts and blockchains, no special solution has been proposed, such as the enactment of the International Unification Act. The blockchain platform which operates smart contracts is decentralized and operates through distributed nodes around the world without central servers, making it difficult to establish jurisdiction and governing laws. As an alternative to traditional dispute-solving methods, a new mediation model-smart arbitration-is being attempted. The arbitration process is likely to be a preferred means of resolving disputes over smart contracts in practice. There are many problems, such as the fairness of the arbitration center on the selection and judgment of arbitrators, the question of securing reliability, the question of the validity of the arbitration agreement, and how much the court can be involved in the case. Preparations at the national level, such as fostering blockchains and smart contract experts, and overhauling the legal system, are needed.

P Leasing Company was a steady growing company with positive net income in most years since 1985 when it was established. However, it suddenly experienced a minus net income of 6.8 billion won in 1996. The reason of its deficit was known to be the financial distress of its two major leasing contracts. The total amount of two contracts was 58 billion won witch is about 8% of total amount of its leasing contracts. In this paper, we analyse how the disability of lease payments from the two leasing contracts influence P Leasing Company's financial stability, growth opportunity, and profitability. In addition, by performing ROI analyse, we point out the financial reasons of P Leasing Company's deficit in 1996. We hope our case analysis to help students understand the cash flow of leasing companies. The P Leasing Company case also illustrates the fact that bad leasing contracts would seriously affect the profitability of leasing companies as bad loans would seriously do the profitability of commercial banks.
