국내 건설수주 규모는 2013년 91.3조원에서 2021년 총 212조원으로 특히 민간부문에서 크게 성장하였다. 국내외 시장 규모가 성장하면서, EPC(Engineering, Procurement, Construction) 프로젝트의 규모와 복잡성이 더욱 증가되고, 이에 프로젝트 관리 및 ITB(Invitation to Bid) 문서의 위험 관리가 중요한 이슈가 되고 있다. EPC 프로젝트 발주 이후 입찰 절차에서 실제 건설 회사에게 부여되는 대응 시간은 한정적일 뿐만 아니라, 인력 및 비용의 문제로 ITB 문서 계약 조항의 모든 리스크를 검토하는데 매우 어려움이 있다. 기존 연구에서는 이와 같은 문제를 해결하고자 EPC 계약 문서의 위험 조항을 범주화하고, 이를 AI 기반으로 탐지하려는 시도가 있었으나, 이는 레이블링 데이터 활용의 한계와 클래스 불균형과 같은 데이터 측면의 문제로 실무에서 활용할 수 있는 수준의 지원 시스템으로 활용하기 어려운 상황이다. 따라서 본 연구는 기존 연구와 같이 위험 조항 자체를 정의하고 분류하는 것이 아니라, FIDIC Yellow 2017(국제 컨설팅엔지니어링 연맹 표준 계약 조건) 기준 계약 조항을 세부적으로 분류할 수 있는 AI 모델을 개발하고자 한다. 프로젝트의 규모, 유형에 따라서 세부적으로 검토해야 하는 계약 조항이 다를 수 있기 때문에 이와 같은 다중 텍스트 분류 기능이 필요하다. 본 연구는 다중 텍스트 분류 모델의 성능 고도화를 위해서 최근 텍스트 데이터의 컨텍스트를 효율적으로 학습할 수 있는 ELECTRA PLM(Pre-trained Language Model)을 사전학습 단계부터 개발하고, 해당 모델의 성능을 검증하기 위해서 총 4단계 실험을 진행했다. 실험 결과, 자체 개발한 ITB-ELECTRA 모델 및 Legal-BERT의 앙상블 버전이 57개 계약 조항 분류에서 가중 평균 F1-Score 기준 76%로 가장 우수한 성능을 달성했다.

블록체인 기술이 부동산 거래분야에서도 활발히 연구되고 있으며 부동산 거래는 다양한 방법이 있다. 본 논문에서는 오프라인상 법원 경매의 문제점을 해결하기 위해 이더리움의 Ether를 사용하여 경매 시스템의 인증 절차를 간소화하는 모델을 제안한다. 제안하는 모델은 이더리움의 Solidity언어로 작성하고 법원에서 매각기일 및 매물의 Meta date를 DApp 브라우저에 등록하고 입찰자는 Meta mask의 Private key를 통해 만들어진 개인의 지갑 주소에 접속한다. 그리고 입찰자는 원하는 매물을 선택, 입찰가격 금액을 입력하여 경매에 참여한다. 입찰자가 원하는 매물의 입찰가격이 가장 높은 입찰자의 기록을 이더리움 테스트 네트워크에 스마트 계약으로 작성하고 블록을 생성한다. 마지막으로 네트워크에서 작성된 스마트 계약은 법원 경매 관리자가 블록체인 네트워크의 모든 노드에 배포하고, 블록체인 네트워크의 각 노드들은 열람 및 계약을 확인할 수 있다. 제안하는 모델의 스마트 계약과 시스템의 성능을 분석한 결과로 이더리움을 이용하는 플랫폼에서 Ether를 생성 및 사용, 그리고 참여로 인해 발생하는 수수료가 있다. Ether의 가치 변화에 따라 매물의 가격에 영향을 끼치며 매번 스마트 계약에서 일정하지 않은 수수료가 발생한다. 하지만 향후 연구에서는 자체 토큰을 발행하여 Ether의 가치 변화에 따른 시세 변동성 문제와 수수료 문제를 해결하며 복잡한 법원경매 시스템을 세분화한다.

This paper analyzes the capabilities of multi-agent system (MAS) technology for the optimal multi-microgrids (MMGs) operation in grid-connected mode. In this system, communication among microgrids (MGs) is realized by developing a modified contract net protocol (MCNP) based on agent communication language (ACL) messages. Moreover, a two-stage mathematical model is proposed based on mixed integer linear programming (MILP) for local optimization in each MG, and global optimization in energy management system.

This study describes the exclusion of the seller's liability for defects in title under CISG and UCC. Through comparing two provisions, this article provides contracting parties with guidance regarding choosing governing laws and practical advice. CISG and UCC states not only the seller's liability for defects in title but also the exclusion respectively. Under two provisions, contracting parties who wish to avoid this liability may agree that the liability will not apply. Under UCC ${\S}$2-213(2), the seller's warranty can be disclaimed by specific language in the contract or by the circumstances surrounding the transaction. Although there is no express exclusion provision under CISG Article 41 and 42, Article 6 allows contracting parties to agree that they may exclude the application of the seller's liability. Both Article 42 under CISG and ${\S}$2-213(3) under UCC provide where the buyer furnishes specification to the seller. Under UCC ${\S}$2-213(3), it is the buyer's warranty to hold the seller harmless from any claims which arise from the seller complying with specification furnished by the buyer. But, under CISG Article 42, the seller's duty is excluded if the third party right or claim result from the fact that the seller has complied with specifications provided by the buyer. Therefore Article 42 does not charge the buyer with the duty, but rather limits the circumstances under which he could cause claims under Article 42. Interestingly, CISG has provisions which are absent from UCC. First, under Article 41, the seller escapes the liability if the buyer agree to take the goods subject to the third party right or claim. Second, under Article 42(2)(a), the seller is not liable if the buyer knew or could not have been unaware of the third party right or claim at the time of the conclusion of the contract.

The purpose of this work aims to analyse the principles of good faith under international transaction with CLOUT and UNILEX cases. Article 7(1) CISG sets the stage for the interpretation by promoting a uniform approach using good faith and the international charter of the convention. In other words, article 7(1) defines the purpose and the principle of interpretation and is applied to the Convention as a whole. As such, it also includes article 7(2), which goes beyond the big picture and settles the problems of gap filling. It is also important to understanding that the mandate of the CISG is to look for a solution, which is not only restricted to interpretation but extends to solving a problem. The problem in this work is to find out how gap filling is achieved and, because of the autonomous mandate of interpretation, to explain and understand its relationship with domestic law. The solution to the interpretation of article 7(2) must be found within the four corners of the CISG. To restate, article 7(2) describes two situations where gap filling is needed. First, if the matter is governed by the Convention but not expressly settled, then a gap must be filled in conformity with general principles on which it is based. Second, if the matter is not covered then the gap must be filled taking domestic law into consideration. There are two reasons why a matter may not be covered by the Convention. First and most obviously, it has been specifically exclude from the sphere of Application by the CISG itself, such as validity in article 4. Second, changes in business methods will lead to gaps. The United Nations has established a service known as CLOUT. This contains abstracts of hundreds of selected decisions of both courts and arbitration tribunals. And UNILEX is cosponsored by the Italian Centre for Comparative and Foreign Law Studies and UNIDROIT Contract Principles. The cases are in abstract format, but, when available, the full text of the case in the original language is also supplied.

The purpose of this paper is to examine the consideration factors, from both parties' perspective, to select the most appropriate arbitral institution when they inset an arbitration clause in their contract. Accordingly, the author analyzed the advantages of institutional arbitration compared to non-institutional arbitration. The typical advantages of institutional arbitration would include: $\bullet$ Benefits of using an established set of rules $\bullet$ Services provided by the institution $\bullet$ Low risks of obstruction $\bullet$ Enhancement of the possibilities of enforcement $\bullet$ Forecast of the estimated cost $\bullet$ Specially useful for existing disputes Next, this author examined the consideration factors when selecting the institution in respect of the following factors: $\bullet$ Institution's arbitration rules $\bullet$ Institution's rule regarding the appointment of arbitrators $\bullet$ Ability of administrators of each institution $\bullet$ Reputation of the arbitral institution and the likability of enforceability of its award $\bullet$ Cost $\bullet$ Choice of the arbitral institution in relation to the choice of place of arbitration Finally, this author reviewed Model Arbitration Clause of major international or local Institutions, including ICC, AAA, LCIA, KCAB, CIETAC, ICSID and WIPO. Further examination was given to the selection of the numbers of the arbitral tribunal, the seat of arbitration and the language of arbitration, according to the designated articles in each institution's arbitration rules.

The purpose of this study was to find out the push and pull factors of migrants from middle Asian countries to Yunhaju, Russia, and housing situations in settlements as well as housing intentions to behave. Four female Korye Saram in Cremobo settlement and Woojung village and 10 male and female elderly in ordinary residences were interviewed during April 22-25, 2003. Changes in national formal language from Russian to lout languages was played the most prominent push role, while availability of settlement and agricultural land and emotional attachment as the second hometown pulled them to migrate into Yunhaju. The housing situation in Cremobo settlement was very poor and almost settlers had already left. The rest settlers wanted to move into Woojung village. The resident in Woojung village hoped to get the formal contract to rent the dwelling and agricultural land. Family adaptations were progressed to solve the housing deficits among settlers both of Cremobo settlement and Woojung village. This research explored a part of the 140 years residential history of Korye Saram.
