This paper aims to construct and analyze the domestic collaborative research network in industrial engineering. Using co-authorship information contained in the papers published in the two journals of the Korean Institute of Industrial Engineers, the collaborate research network at the institutional level is constructed. The core institutions in the network are identified by means of the centrality indexes of social network analysis. In addition, the five types of roles of the institutions in industry-university-institute cooperation are examined through brokerage analysis: coordinator, consultant, gatekeeper, representative, and liaisons. The findings are expected to be fruitfully utilized in formulation of R&D strategy of relevant organizations and technology policy making for promoting collaborative research in industrial engineering.

Maintaining online services of high quality has become a crucial factor for brokerages to gain competitive advantages. Because of the attributes of the product uniformity of online trading, online brokerages have grown significantly with IT development, since the early 2000s. Now, as the online trading business gets mature, the profitability of the IT investment and the quality of IT-based services became questioned. This study examines the issues of IT investment and its contribution by analyzing the relationship between the quality of online service and IT investment. In addition, it also investigates the relationship of the quality of online services and profitability of brokerage. Our results show that IT investment draws cubic-style, curvilinear relationship with the service quality of online trading and only high quality services can lead to the increase of profitability.

클라우드에 대한 범용적인 관리를 위해서 사용되는 CSB(Cloud Service Brokerage) 기술을 기반으로 실제 사용자들이 이용하는 서비스를 제공하는 어플리케이션을 제공하기 위한 모델로 PaaS(Platform as a Service)이 도입이 되어야 한다. 이러한 구조 제공을 위해서는 CSB 서비스의 특성과 Application 구성 요소에 대한 관리 체계에 대한 접근을 통해서 다양한 클라우드에서 호환성을 보장할 수 있어야 한다. 본 논문에서는 기존에 활용되는 도구들의 제약 사항과 함께 클라우드 기반 마켓플레이스를 통해 다양한 IT 서비스를 생산 및 유통할 수 있는 구조에 대해서 고찰하고자 한다.

클라우드 컴퓨팅 기술로 인한 정보기술 영역의 파라다임의 변혁에 따라서, 다양한 산업의 기업들이 운영비용 및 투자비용 절감효과를 목적으로 클라우드 컴퓨팅을 도입하며 성공 사례를 논의하고 있으나, 기업의 프로세스 개선을 위하여 클라우드 서비스를 이용하는 접근방법은 아직 국내 사례에서는 부족하다. 본 논문에서는 클라우드 서비스를 관리하는 CSB(Cloud Service Brokerage) 플랫폼에서 서비스의 Orchestration을 지원하는 SOA(Service Oriented Architecture)의 WS-BPEL 기술을 적용하여 프로세스 자동화를 구축할 수 있는 아키텍처를 제시하였다. 클라우드의 SaaS 도입 시 어플리케이션뿐만 아니라, 인프라 서비스를 이용하는 IaaS 적용과 다른 프로세스와의 호환과 연동 작업을 구축하는 PaaS를 같이 적용함으로써 비즈니스 프로세스의 가치 향상이 가능하도록 본 논문에서는 클라우드 서비스 브로커 도입에 대한 시스템 아키텍처를 제안한다.

The purpose of this study is to identify the consumer factors influencing the channel choice in the brokerage transaction. The 14 consumer factors were extracted from the two perspectives: first, the off-line channel is based on the relational benefits offered by the salespeople, second, the on-line stock exchange is a transaction mediated by the internet technology. The results shows that the channel choice is significantly influenced by the 8 out of 14 consumer factors hypothesized: interpersonal orientation, risk-taking tendency, amount of money invested, price consciousness, time length of internet usage, innovativeness, information privacy sensitivity, intrinsic desire for information. And the results of discriminant analysis shows that three consumer factors-risk-taking tendency, time length of internet usage, and information privacy sensitivity-are most valuable in discriminating off-line vs. on-line customers.

Recently, the number of available cloud services are increasing dramatically because many IT companies have entered into cloud service market. Due to the reason, cloud service brokers are emerging as agents to solve cloud service selection problems and to support cloud service initialization and maintenance of unskilled cloud service users. In this study, NCloud24 case in South Korea and Right Scale case in the USA are analyzed as representative examples of the collaboration between original cloud service providers and cloud service brokers. The business models of two companies are analyzed using Business Model Canvas. The emergence of cloud service brokers are interpreted as unbundling process of IaaS (Infrastructure-as-a-service) cloud service companies. Based on the comparison with the two companies, we prospect future directions of cloud service brokerage.

This paper investigate to test the validity of the basic assumptions of strategic trading models with the broker and informed trader using daily closing data of KOSPI 200 stock index futures for the year 2001-2003. Major results are summarized as follows: (i) For these years, while foreign investors and brokerage companies traded for the directions consistent with the model, brokerage companies and individual investors traded for inconsistent directions. (ii) Cross correlation function (CCF) analysis shows no systematic dependency in the trading between all three participants(foreign investor, brokerage companies and individual investors) for these years. (iii) Chi-square validity test for the 30 days of the largest unexpected trading volume shows some systematic dependency in the trading between three participants for these years. Finally, some limitations of this paper and direction for further research were suggested.

Recently, renewable energy-related power generation facilities have been surging due to the government's "Renewable Energy 3020", "Green New Deal", "2050 Carbon Neutrality" and "K-RE100" policies. Most renewable energy facilities are small and distributed, making it difficult to manage efficiently, and small distributed resources less than 1MW are having a hard time with participating in the market due to the limited sales and avoidance of trading. In particular, the intermittency of renewable energy has a significant impact on the stability of the power grid. The government is seeking to address volatility and intermittency issues through 'small distributed resource brokerage trading, and to expand the systematic resourceization and acceptability of heterogeneous large and small distributed resources. In this work, we intend to apply an AI-based power generation prediction model to a distributed resource brokerage trading system so that it can be utilized as a foundation platform for pioneering new energy business markets.
