이상완,최형림,박남규,김현수,박병주,유동호 한국로지스틱스학회 2002 로지스틱스연구 Vol.10 No.1

급속한 세계화로 터미널간의 경쟁이 치열해지면서 기존 시설의 효율적인 운영 및 관리가 터미널의 경쟁력과 생산성을 향상시키는 중요한 요소로 부각되고 있다. 하지만 우리나라 컨테이너 터미널은 양적 확장에 치중한 반면 관리와 운영의 효율성에 대해서는 다소 소홀히 해 왔다. 그리고 대부분의 컨테이너 터미널은 자사 운영시스템을 저문 업체에 의뢰하여 개발함으로써 컨테이너 터미널마다 상이한 시스템이 구축되어 시스템의 유지 보수비용이 많이 발생하고 있다. 최근 터미널 개발과 운영 자체가 사업화 되고 있기에 향후 터미널 운영시스템에 대한 수요는 증가할 것이다. 그래서 터미널마다 다른 운영시스템을 표준화하고 국제화한 ERP 형태의 통합 운영 시스템의 개발이 요구된다 하겠다. 따라서 본 연구에서는 주문형 방식에 의존하던 컨테이너 터미널 운영시스템의 고비용, 비 통합화, 개발기간의 장기화 등의 단점을 극복하기 위해 컨테이너 터미널 ERP 시스템이란 새로운 개념을 제안한다. 이 컨테이너 터미널 ERP 시스템은 통합된 운영시스템 구축, 개발기간의 단출, 개발비용의 절감, 쉬운 업그레이드를 가능하게 해 컨테이너 터미널의 글로벌 사업에 전략적 도구로써 역할을 하게 될 것으로 기대된다. The major characteristics of ERP(Enterprise Resource Planning)are enterprise-wide system that covers all the business functions and information resources, integrated database, built-in best industry practice, packaged software and open architecture. ERP enables reduction of system development time, flexibility, standardization of workflow and effective business planning capability. ERP is mainly for manufacturing industry. However, the principles of ERP can also be applied to container terminal. We have clustered the workflow of container terminal, and analyzed the business process to generate the best workflow. The integrated database is designed to eliminate redundancy and keep integration. The core of ERP for container terminal is the planning facility such as berth planning and yard planning. The planning capability is very tightly coupled with data flow from client entities such as shipping companies. The ERP can handles the existing problems of container terminal operation that are mainly caused by lack of integration of whole of information resource in container terminal, ad-hoc and poor planning capability, disconnected and incorrect data from client companies. ERP approach not only van resolve the problems of container terminals but also promote adoption of information systems for container terminals in the world that have not yet implemented terminal operation systems.

Hyung-Rim Choi,Nam-kyu Park,Young-Jae Park,Yong-Sung Park,Si-Hyeob Kang 한국항해항만학회 2003 한국항해항만학회지 Vol.27 No.3

Off line ship chartering is done nearly through the brokers. Because of the international scale of chartering market, brokers spend too much times and costs on searching the most appropriate product which the consumers want. In this research, we propose the on-line Charter Product Categorization Model to search the products efficiently in the Cyber Chartering System. This Model will make concerned parties of the ship chartering to get unified product information efficiently, and to select the most appropriate product. In this research, we classified the ship chartering products into categories of cargo, ship type, and sea routes, and defined mutual relation of each products. and we verified that this classification is necessary to search the products through the product searching experiment.

Choi, Yeon Ja,Kim, Hyung Suk,Lee, Juyoun,Chung, Jin,Lee, Jun Sik,Choi, Jae Sue,Yoon, Taek Rim,Kim, Hyung Keun,Chung, Hae Young 대한약학회 2014 Archives of Pharmacal Research Vol.37 No.8

Oxidative stress has been proposed to be a major cause of aging and many age-related diseases. Peroxynitrite ($ONOO^-$), formed from the reaction of superoxide ($^{\bullet}O_2{^-}$) and nitric oxide (NO), is a cytotoxic species that can oxidize various cellular components, such as proteins, lipids, and DNA. The present study investigated whether dimethyl lithospermate (DML), isolated from Salvia miltiorrhiza, modulates age-related increases of $ONOO^-$, NO, and reactive species (RS) levels and expressions of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS). For this study, 20-month-old rats were intraperitoneally injected with 5 or 10 mg/kg/day of DML, and 6-month-old rats were used as young control animals. Our results indicated that DML reduces $ONOO^-$ levels in a dose-dependent manner. The data also revealed that DML has significant inhibitory effects on NO metabolites and RS generation in a dose-dependent manner during aging. Furthermore, the results of Western blot analysis revealed that DML treatment reduces age-associated increases in COX-2 and iNOS expressions. Thus, this study found that DML caused the decrease of renal oxidative stress and COX-2 and iNOS expressions in aged rats. The significance of the present study is the finding of DML in its potential application against the aging process.

Choi, Hyung-Rim,Park, Nam-Kyu,Lee, Hyun-Chul,Seo, Young-Joon,Shin, Joong-Jo Korea Association of Information Systems 2005 情報시스템硏究 Vol.14 No.3

Compared with land logistics and sea logistics, air logistics takes not only less transportation time, but also makes just-in-time delivery possible. Because of this, in spite of high freight rates, many shippers make good use of airlines. To cope with borderless competition in this global age, most shippers using air logistics want to receive diverse information including just-in-time cargo delivery and dangerous situation as well as convenience and speed in job handling. Nevertheless, most domestic forwarders, who perform many kinds of important businesses for air logistics, mainly put emphasis on demanding information from overseas partners through their business agreements, that is, focusing on horizontal integration, instead of sharing information or improving job performance among air logistics participants. As a result, it is almost impossible to satisfy the needs of shippers. Airline users want to remove the uncertainties over their cargo movement. And in time of emergency, they want to take immediate measures through speedy information sharing and decision-making. In order to satisfy shipper's needs, all the organizations participating in the air logistics supply chain-cargo senders, cargo receivers, forwarders, transporters, licensed customs brokers, airlines as well as foreign partners-have to set up a vertical cooperation system. For effective air logistics SCM, it is very important to remove overlapping jobs, strengthen the efficiency of job handling, and provide online monitoring on cargo information in order to support decision-making. To this end, this paper has applied the concept of RTE (Real Time Enterprise), a new business management system, which tries to maximize competitiveness by removing many hindrance factors on an ongoing basis in managing and fulfilling core business processes based on up-to-the-minute information. In order to realize RTE-based information system for air logistics SCM, this paper has analyzed the information required by business process and by air logistics participant, and suggested the method for information sharing, point of time for information input and output, and its means.

Hyung Rim Choi,Sung Il Byeon,Chang Hyun Park 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.8

In line with the ever-tightening environmental regulations, countries all over the world are exerting efforts for the establishment of eco-friendly policies. Also, in the area of maritime and ports, the greening of the maritime and ports logistics area is emerging as an urgent task because of the serious level of pollution and increased carbon emissions in port regions. In order to respond to climate change within this age of “low-carbon green growth,” the construction of eco-friendly green ports becomes increasingly important. As such, many countries in the world are making various efforts to establish policy directions for the construction of eco-friendly ports. To reduce greenhouse gas, a systematic and reliable estimation system is very important. Accordingly, this research developed and suggested a system that can estimate CO2 emission from port facilities for the construction of green ports and the reduction of carbon emissions. It is expected that this system will be used as a basic data system in the policies for climate change response and greenhouse gas reduction, thus providing a more efficient management of carbon through a dimensional analysis of its emission sources.

Cyber Shipping Exchange : Design Principles

Choi, Hyung Rim,Park, Nam Kyu,Kim, Hyun Soo,Park, Young Jae 동아대학교 경영대학 2002 經營硏究 Vol.- No.15

Cyber exchange is a cost-effective approach to trading goods and information among multiple sellers and buyers. The Shipping industry includes many global entities such as shippers, liners, ship owners and shipping agents. Marine insurance companies and ship repairers and many other groups are also supporting the industry. However, international shipping exchanges are located in only a few cities around the world. It's our belief that a shipping market can operate online so that market participants conduct their dealing while residing where they are with more efficiency manner, preferable prices and with a larger pool of potential trading partners. This paper presents a Korean government's project for building a cyber shipping exchange. The exchange covers ship sales and purchases, charters and freight futures. The workflows of each business were analyzed and designed to fit an online environment. The project includes the design of trading mechanisms, online documents, data flow, data storage and security. Online match making and trading mechanisms such as auction, reverse auction, and bid are used. The whole trading process involves multiple organizations and business processes. So, this paper focuses on how each organization would play their roles so users can complete transactions with an integrated and transparent view. The cyber shipping exchange serves also as maritime portal site that links to other sites for vertical and horizontal cooperation, and serves as a database of information with a global perspective. This paper also issues and discusses the justification of an online shipping exchange.

A Design of Multi-Agent Framework to Develop Negotiation Systems

Hyung Rim Choi,Hyun Soo Kim,Soon Goo Hong,Young Jae Park,Yong Sung Park,Moo Hong Kang 한국지능정보시스템학회 2003 지능정보연구 Vol.9 No.2

A multi-agent technology has emerged as new paradigms that can flexibly and promptly cope with various environmental changes and complex problems. Accordingly, many studies have been carried out to establish multi-agent systems in an effort to solve dynamic problems in many fields. However, most previous research on the multi-agent frameworks aimed at, on the behalf of a user, exchanging and sharing information among agents, reusing agents, and suggesting job cooperation in order to integrate and assimilate heterogeneous agents. That is, their frameworks mainly focused on the basic functions of general multi-agents. Therefore, they are not suitable to the development of the proper system for a specific field such as a negotiation. The goal of this research is to design a multi-agent framework for the negotiation system that supports the evaluation of the negotiation messages, management of the negotiation messages, and message exchanges among the negotiation agents.<br/>
