Existing real estate markets are monopolized because they are capital intensive and have information asymmetry. However, with the advent of the Fourth Industrial Revolution, technology is converging in various industries based on information technology (IT), and the real estate market is also developing a new field called "PropTech". According to this trend, new PropTech technologies are emerging in various real estate services sectors in Korea, but the electronic contract system, which accounts for the largest portion of the real estate industry, is still cited as a complex identification process and long processing time. Therefore, in this paper, we propose an improvement plan for the current electronic contract system through the introduction of blockchain technology, which is drawing attention with the development of PropTech, and explore the possibility of introduction by producing an experimental model of blockchain-applied electronic contract system in a programming language.

본 연구는 대규모 유가공업체 매일유업과 전라북도 고창군 낙농가 간 유기농 원유 계약생산을 대상으로, 계약생산이 고창군에서 시작된 배경을 고찰하고, 계약생산의 실제와 계약주체 간 관계를 중심으로 계약생산의 특징을 규명하고, 이로 인해 나타나는 지역 낙농업의 변화를 설명하였다. 사례지역의 유기농 원유 계약생산은 시장개방으로 위기에 처한 기업의 제품 다각화 전략과 고창군의 청정 환경, 그리고 지방정부와 낙농가의 긍정적 태도가 맞물리면서 성립되었다. 고창군의 유기농 원유 계약생산은, 한편으로는 참여 농가의 생산규모를 선택적으로 증가시킴에 따라 역내 낙농가 간 생산규모의 격차를 유발하고 있으나, 다른 한편으로는 계약농가의 유기농가로의 전환을 통해 역내 유기농업의 확산을 가져옴에 따라 관행농업 중심의 계약생산에 대한 일반의 우려를 불식시키고 있다.

A nuclear power plant construction is a complex form of construction which comprises various stakeholders and contractors. Therefore, contract disputes will occur due to conflicting interests of contracting parties and unpredictable factors which arise during construction work. Even if the contract is well prepared, it cannot fully prepare for future situations in actuality. Claims management is very important in carrying out construction management. This study intends to define claim, and delve into development of claims management processes from the viewpoint of owners and contractor through consideration on international contract terms on claims management and the details of the claims management of the Construction Extension to the PMBOK. In addition, it is needed to accumulate and manage data on claims that have occurred so that they can be referenced in the future. As information should be accumulated so that type classification can be carried out and that lessons can be learned on claims that have occurred in each business site, study on establishing data-based systems relating to claims processes will be needed in the future.

Since the sub-prime mortgage crisis from the US in 2008, the Korean housing market has plummeted. However, the deposit prices of the Korean local lease contract, Chonsei, had been increasing. This increase of Chonsei prices can be a threat to low-income people, most of whom prefer to live in houses with a Chonsei contract. In the housing and Chonsei market, there are many stakeholders with their own interest, hence, simple thoughts about housing and Chonsei market, such as more house supply, will decrease house price, would not work in a real complex housing market. In this research, we suggests system dynamics conceptual model which consists of causal-loop-diagrams for the Chonsei market as well as the housing market. In conclusion, the Chonsei price has its own homeostasis characteristics and different price behavior with housing price in the short and long term period. We found that unless government does not have a structural causation mind in implementing policies in the real estate market, the government may not attain their intended effectiveness on both markets.

공공건설사업은 국가경제에서 막대한 영향을 미치며, 투입되는 인력도 다양하다. 그리고 공공건설사업이 복잡해지고 다양해짐에 따라 하자발생 가능성이 매우 높다. 그러나 수급인이 부담하는 하자에 대한 책임을 민법과 국가계약법령에서 채무불 이행책임과 하자담보책임으로 이원화하고 있음으로 인해 해석내용이 다양하며, 실제 건설현장에서는 하자책임에 대한 해석이 불분명함으로 인해 분쟁의 요인이 되고 있다. 따라서 본 연구에서는 하자책임과 관련하여 해외의 동향을 살펴본 후, 우리나라 민법 및 국가계약법령의 하자책임 및 그와 관련된 문제점을 살펴보고, 하자에 대한 수급인의 책임정립방안을 제시하고자 한다. 본 연구 결과 도출된 공공건설사업의 하자에 대한 수급인의 책임 정립방향을 요약하면 다음과 같다. (1) 하자 발생시 하자에 대한 책임을 불완전이행으로 인한 채무불이행책임으로 일원화하여 수급인에게 적용하는 것이 바람직하다. (2) 손해배상의 범위는 보수비의 과다 및 하자의 중요성을 고려하여 결정해야 한다. (3) 소멸시효의 기준이 되는 하자책임시점은 계약이행중에는 기성검사이후부터 불완전이행으로 인한 채무불이행책임을 부담시키고 있으므로, 기성검사를 완료한 날부터 기산할 수 있다. (4) 현행 계약이행보증제도의 하자보수책임을 제외하고 계약이행도중 기성검사를 완료한 부분에 발생하는 하자를 담보하기 위하여 유보금제도를 도입해야 할 것으로 판단된다.

This study is to analyse the applicability of governing law in multi-party contractual relationship of letter of credit. And this study is also to suggest the limits of the possibility of applicable law in multi-party contract. The contract of letter of credit constitutes complex relationship, i.e., applicant -beneficiary, applicant-issuing bank, issuing bank-intermediary bank ect. The law applicable to letter of credit should not use a singular governing law in all credit transaction as sales contract. To solve these problems, the author analysed the law applicable to the credit under multi-party contractual relationship as follow : (1) the principle of party autonomy (2) In the absence of express agreement with regard to the law applicable to the contract, lex loci contractus, lex loci solutionis, the law intended by the parties, the law with which contract is most closely connected. Accordingly, when attempting to ascertain the law governing the credit, it should be borne in mind that the credit involves several contractual relationships. I would like to conclude as follows: 1. The contract between the applicant and the Issuing bank is to be governed by the law of the country where the contract is made, and in which the bank carries on business and has issued the credit. 2. When it comes to the beneficiary-Intermediary bank relationship the following rule is given : The liability of an intermediary bank to the seller is governed by the law the country where the intermediary bank is operating if it is acting as principal. If, however, it is acting as agent(advising bank), it will be the law of the country where his principal is situate. 3. The contract between the beneficiary and the Issuing bank is governed by the law of the country where the payment is to be performed. 4. The contract between the Issuing bank and Intermediary bank is governed by 1) the law of the issuing bank is applicable if the intermediary bank only advises the credit, 2) the law of the issuing bank is applicable but if the intermediary bank makes payment, accepts or negotiates drafts against the tender of the documents, i.e., act as the bank dffecting the payment., 3) the law of the confirming bank is applicable if the irrevocable letter of credit is confirmed by the intermediary bank

최근 한국의 대규모 IT 서비스 프로젝트의 수익률은 저하되고 있는 것으로 파악된다. IT 서비스 프로젝트의 수익률을 저하시키는 가장 큰 이유는 프로젝트와 관련된 여러 위험 요인들이 프로젝트의 일정 지연 및 비용 초과를 초래한 것으로 파악 된다. 이러한 일정 지연 및 비용 초과 현상을 방지하기 위해서는 프로젝트의 위험 요인들을 계약 체결 전에 식별하는 것이 매우 중요하다. 왜냐하면 발주사와 개발사간 계약 조건 협상 시 식별된 위험 요인들을 제거할 수 있기 때문이다. 본 연구에서는 IT 서비스 프로젝트의 특성으로 인해 프로젝트 수행 과정에서 발생할 수 있는 계약 위험 요인들을 사전에 파악하고 평가할 수 있는 체크리스트를 제시하고, 이를 실제 금융 산업의 IT 서비스 프로젝트에 적용하여 그 효과를 확인하고자 하였다. 적용 사례를 분석한 결과 IT 서비스 프로젝트의 위험 요인들을 식별하고 제거하는데 본 연구에서 제시된 체크리스트가 효과가 있음을 확인하였다.

Purpose - This research empirically proves that global shipbuilding industry leadership has moved to China from Korea. Design/Methodology - Competitiveness is measured by AHP for the weights of comprehensive competitiveness, which is the output mixture of three attributive factors: shipbuilding technology, shipbuilding contract price, and export credit. Findings - China is far ahead of Korea for standard vessels such as bulkers and containerships with competitiveness weights of 0.762 and 0.612, respectively, against 0.238 and 0.388 of Korea. Korea is maintaining its competitiveness only in LNG carriers (174k CBM) with a competitiveness weight 0.621. China and Korea have similar competitiveness for chemical carriers, complex vessels with a small hull size. The sources of Chinese competitiveness are shipbuilding contract price and export credit. With the majority share of standard vessel types in the world fleet, China will hold a bigger market share than Korea in the global shipbuilding industry in the forthcoming years. Implications - The swing factors of market power are shipbuilding technology and contract price. If China fails to further develop shipbuilding technology for shipowners worried about the reliability of the Chinese-built vessels, shipowners may swing back to Korea. The rising Chinese labor cost will expedite this swing in the forthcoming competition. Originality/value - To the best of the author's knowledge, this is the first paper that quantitatively examines the competitiveness of shipbuilding between China and Korea by comparing attributive factors for competitiveness.

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.
