해양수산부와 산업통산자원부가 공동으로 추진하고 있는 자율운항선박 기술개발 프로젝트의 핵심기술은 지능항해시스템, 기관자동화시스템, 성능실증센터 및 실증기술, 운용기술 및 표준화로 나누어지며, 대한민국은 2025년까지 자율운항수준을 대양에서는 IMO Level 3, 연안에서는 IMO Level 2까지 달성하는 것을 목표로 하고 있다. 한편, 삼면이 바다로 둘러싸인 대한민국은 세계물류 이동의 거점임과 동시에 어선 등록 척수가 매년 6만 5년여 척이 넘는 어업이 활성화된 나라이며, 주요 어업 해역인 남해안은 대표적 무역항인 부산항, 광양항 등으로 통하는 항로와 중첩되기 때문에 자율운항선박의 원활한 운항을 위해서는 어업이라는 변수가 반드시 고려되어야 한다. 이 연구에서는 핵심기술 중 지능항해시스템 기술개발과 관련, 어업이 지능항해에 미칠 수 있는 영향을 어구, 어법, 어선으로 분류하여 고찰하였고, 발생 가능한 변수를 줄이기 위한 연구 방향을 제시하였다.

This study was conducted to find ways to expand investment and seek cooperation measure in Cambodia. It is located on the Indochina Peninsula in East Asia, and has historically suffered a lot from social systems and politics. It is a politically constitutional monarchy and shows a neutral tendency in the form of a non-alliance of pro-Westernism. Cambodia recently recorded a high growth rate due to the economic liberalization promoted since the mid-1980s. It is also emerging as the next generation production base in Southeast Asia. The diplomatic relationship, which had been temporarily suspended with Korea, was resumed in 1997. Since then, it has been conducting mutual trade and exchange. Therefore, this study which is as unfamiliar and infrequent looked at Cambodia's economy, trade trends and support plan. In addition, various development possibilities were considered. In particular, in-depth research was conducted on local entry methods and participating projects. First of all, it was devised various ways to expand investment and human exchange, diversify public-private relations, and enter the logistics, distribution, and infrastructure projects directly. As such, this study was developed to serve as a basis for contributing to a part of the research on Cambodian economy and trade in the future.

On public constructions, that the first planed projects delay than the scheduled completion day occurrence frequently because gap between the scheduled construction durations and the actual construction durations. These facts connect with not only problems of the construction during as the construction delay but also brought about the distribution costs increase as the failure of facility use plan and the people discomfort weight, failure of the production and the supply using facility then tremendous loss of each part etc. For reduce these loss, it must improve accuracy of the scheduled construction duration estimating when it order. This study try contribute to a successful manage of public project and reduce the construction duration extension frequent of the construction during, and then ensure the suitable construction duration by present the estimation model of the scheduled construction duration that include the construction duration correct element using as an index on the scheduled construction duration estimation.

Modern cities are changing to 'smart cities' dramatically with the introduction and development of the fourth industrial revolution technologies. Among these technologies blockchain is unique because it not only embraces technological innovation but also societal revolution. Therefore, blockchain is expected to play a pivotal role for contributing comprehensive development of smart city. The current research and policy atmosphere in Korea, however, is that blockchain is just a new technology and its broader impacts are overlooked. This study argues that blockchain has significant effects on smart cities not only from technological perspectives but also from social, economic, institutional, governmental perspectives. Further, this study suggests three categories that blockchain can help the development of smart city: technology, socio-economic, and governance, with examples of existing blockchin projects. However, these projects have been builting separately without any interaction under the common hood of 'smart city'. To emhance influences of blockchain on smart cities in positive ways, private companies, policy maker, and citizend are supposed to consider and discuss about publi sector's blockchain that is commonly used in at the smart city level.

In construction industry, the cost related to material is different from each other under the characteristic of projects. However, it has 40% of the whole cost in the composition of prime cost. Recently, While the construction work become bigger, specialized and complex, it is complex to carry in materials because of shortage of space. However, in many cases, material management has been underestimated as well as the material management is depending on experience of site managers so it has been studied about frequently. In this study, I suggest four classification methods of material characteristic ETO, ATO, MTO, MTS. I also analyze what the most efficient supply management of the site materials is through researching the characteristics of the material distribution. In conclusion, I would like to build the material management classification for the characteristics of materials.

In general, material cost of a construction project is more than 30$^{\sim}$40% of total construction cost, thus on site material control is very important. The factthat buildings have recently become higher and bigger also increases the importance of on site material control. However, on site material control has not been considered as an important management issue. This study classifies building construction materials considering the material delivery characteristics such as ETO, ATO, MTO and MTS and the unique characteristics of each materials. Using the classification, this study examine the requirements for on site material control of each materials. Finally, this study suggests on site material control systems for each construction material.

The purpose of this study is to develop the process to support and evaluate experts' decision making on vertical transportation planning in high-rise building constructions. Experts generally carry out the vertical transportation planning by heuristic methods, so there is a possibility that their decisions failed. The failure of the vertical transportation planning can be result in much loss of time and cost. The process presented in this paper evaluates experts' alternatives, organizes the results of the vertical transportation plan, and then leads to the systematic flow of materials and crews.

사물인터넷 비즈니스의 수요가 증가하면서, 다양한 사물들에 대한 식별 및 데이터 공유 체계와 서비스 디스커버리 표준을 제공하는 GS1 (Global Standard 1) 국제 표준이 글로벌 사물인터넷 표준으로써 자리잡고 있다. 유통/물류분야의 지배적 표준에서 시작한 GS1은 1999년 세계 최초로 사물인터넷(Internet of Things)이란 용어와 개념을 소개한 이후, 스마트팩토리, 헬스케어 서비스 표준에서부터 금융 서비스에 이르기까지, 다양한 산업 도메인 응용의 수평적 통합을 가능하게 하는 데이터 기반의 사물인터넷 표준으로서의 입지를 지속적으로 확장해 나가고 있다. 본 논문에서는 GS1 국제 표준에 대한 전반적인 개념 및 특징을 설명하고 현재 활발히 진행되고 있는 다양한 서비스 표준안들과 GS1 표준의 레퍼런스 구현인 Oliot(Open Language for Internet of Things) 오픈소스 프로젝트를 소개하고, 실제 글로벌 비즈니스에서의 적용 사례들을 살펴봄으로써 사물인터넷 비즈니스 플랫폼으로써의 GS1 표준의 전망을 제시한다.
