This study aims at classifying and analyzing the business models of reverse overseas direct purchasing through online shopping-malls. After analyzing the current status of the reverse overseas direct purchasing online markets, this study identifies relevant critical business factors and synthesizes prior studies to construct and analyse the business models. This study proposes that the business models can be classified into five types according to the operation modes and three types according to the delivery methods. So theoretically 15 business models can be identified. For each business model this study analyzes the characteristics and the pros & cons. It also suggests deployment strategies for companies by considering cost reduction, brand establishment, customer management, customer aquisition, and easiness from the business perspective. From the customers perspective, cost reduction, reliability, royalty, ease to purchase, and accessibility can be considered according to the types of operation mode. The main contribution of this study is to provide the basic classifications and structures of reverse overseas direct purchasing business models systematically. As the result, our study evaluates the business models that which one is better than others in a situation in terms of company and customer. Lastly, we talk about limits and future prospects of the study.

임규건(Gyoo Gun Lim),류미나(Mei Na Liu),이정미(Jung Mi Lee) 한국IT서비스학회 2017 한국IT서비스학회 학술대회 논문집 Vol.2017 No.1

한국은 단기간에 IT강국으로 급성장함에 따라 사이버상의 각종 부작용이 새로운 사회적 문제로 부각되고 있다. 사이버상의 부작용으로는 사이버 폭력, 개인정보 유출, 사이버 테러 등이 있는데 전 세계적으로 개인정보 유출에 대한 심각성이 대두되고 있다. 이런 개인정보 유출로 인한 피해비용을 산출하는 연구는 해외에서는 다양하게 이뤄지고 있지만 국내에서는 미흡한 상황이다. 본 연구에서는 개인, 기업, 국가 기준에서 개인정보유출로 인한 피해비용을 실거래 평균값 기반, 개인 인식 가치 기반, 보상금액 기반, 타 국가 기반 등 총 4가지 방법으로 산출하는 방법을 제시하고자 한다. 이러한 산출모델을 통해 개인정보 유출로 인한 피해비용을 줄일 수 있는 방안 마련의 지표로 사용될 수 있을 것으로 기대한다.

임규건(Gyoo Gun Lim),이대철(Dae Chul Lee) 한국IT서비스학회 2012 한국IT서비스학회지 Vol.11 No.2

The G2B system is one of the important information systems in the e-government implementation. It is difficult to measure the cost reduction effect of the system introduction because there are many participants in the complex procurement processes. Previous approaches of the performance evaluation of such processes have been based on conducting some surveys and interviews with statistical methods. Therefore there have been some limitations in the verification of feasibility. Therefore this study tries to suggest a case of performance evaluation about the cost reduction in using of the G2B system by analyzing operational DB data from the G2B system. This study analyzed the procurement processes of G2B system according to ‘goods’ and ‘facilities/services’ and classified the procurement processes into 12 sub-processes. By developing an evaluation model for the cost reduction of e-procurement, we derived the whole cost reduction effect was 8,000 billon Won for the use of Korea KONEPS G2B system in 2008. Specially the cost reduction in the private sector was 6,600 billion Won. It was mainly due to the decrease of the offline visits to the related organizations to participate a bidding process. Moreover, the cost reduction of using shopping mall was 1,000 billion Won among the total 1,400 billion Won in the whole public sector. The main contribution of this paper is to show the more objective evaluation result of the use of e-procurement, which verifies the necessity of G2B system.

  The current software company report system in Korea has many problems in its efficiency and effectiveness. In this paper, we investigated the system by surveying the contracting officials and contractors in software development. By analyzing current status and some problems with the survey results, we derived an feasible improvement scheme for the software company report system. We suggested efficient procedures and reporting items for the registration process, some benefits for contractors, and the short-term direction for its implementation.

임규건(Gyoo Gun Lim),박인섭(In Sub Park),이대철(Dae Chul Lee) 한국IT서비스학회 2007 한국IT서비스학회지 Vol.6 No.2

  Nowadays, IT becomes one of the core competencies in a business. So defining appropriate responsibilities & roles of IT human resources as well as setting the professionalism of them is getting more important. However, there are lots of problems between the supply and the demand of IT human resource. The efforts to arrange workers who have expert knowledge and skill in right place are needed to strengthen national competitiveness. Recently, several leading countries are setting IT skill standards to solve such problems. Therefore, this paper aims at analyzing IT skill standards of developed countries such as ITSS of Japan, SFIA of United Kingdom, and SSIT of USA. By doing comparative analysis of current status of Korea with them, we derive some meaningful insights to develop a national IT skill standard.

SW개발 SI 프로젝트 과업내용변경에 대한 대가 조정에 관한 연구

임규건(Gyoo Gun Lim),김중한(Joong Han Kim) 한국IT서비스학회 2005 한국IT서비스학회지 Vol.4 No.1

Generally SW industry is considered as a high value-added business area. However, many SI companies in Korea have been loosing profits in public business sector. One of the reasons of this problem is because the compensation for the change of work which occurs frequently during a project has been rarely happened. This might be because many contracts have been made as more officer-oriented one. So far, there has not been much study on this topic. So in this paper, we are going to define the change of works in SI projects, analyze the characteristics, and classify them into some categories. After analyzing the current status and related laws concerning this problem, we will suggest a way to solve this problem and show the future research topics.

전자상거래의 발전과 온라인 마일리지, 포털머니, 게임머니 등 비즈니스모델의 다변화로 사이버머니 시장이 발전하였다. 그 규모는 지속적으로 성장하여 이에 관련된 시장의 분류, 현황 및 문제점, 이슈에 대한 연구의 필요성이 높아지고 있는 시점이다. 따라서 본 연구에서는 사이버머니에 관련된 기존문헌 분석을 통하여 탐색적 연구를 시행하였다. 이를 통해 사이버머니의 범위를 설정하고 사이버머니 분류지표를 제시하며 사이버머니의 발전에 대한 이슈와 사이버머니 시장현황에 대한 현황을 살펴본다. The cybermoney marketplace has been improved by many changes of a business model, such as the development of online exchange, online mileage, potalmoney and gamemoney and so on. Because of its continuous growth, the need for categorizing manketplaces and researching on cybermoney marketplace status and problems has been increased. Therefore, in this paper, We researched about cybermoney marketplace's status and problems. We suggest the indicator that could classify cybermoney. We examined the status of cybermoney marketplace and identified the issues of development of cybermoney.

임규건(Gyoo Gun Lim) 한국지능정보시스템학회 2007 지능정보연구 Vol.13 No.4

인터넷의 대중화와 e-비즈니스의 활성화에 따라 향후 인터넷과 유비쿼터스 환경에 대비한 지능형시스템 연구가 가속화 되고 있다. 전문가시스템도 기존의 Stand Alone방식에서 웹기반의 클라이언트-서버방식으로 발전되고 있으며, 다양한 인터넷 환경에서 활용되고 있다. 본 논문에서는 인터넷 웹 환경에서의 전문가시스템 개발환경과 고려사항들을 살펴 보고 웹 기반 전문가시스템들을 유형별로 분류하고, 분석하여 이를 통해 웹 기반 전문가 시스템의 일반적인 유형 모델과 구조를 제시한다. 본 논문에서는 첫 번째 클라이언트와 서버 간의 Load Balancing 측면에 따라 서버중심의 Server Oriented, 클라이언트 중심의 Client Oriented의 두 가지 모델을 구분 하였다. 그리고, 두 번째 지식 및 추론 공유 정도에 따라 지식과 추론에 대한 공유가 전혀 이루어 지지 않는 No Sharing, 서버들 간에 지식 및 추론의 공유가 이루어지는 경우인 Server Sharing, 클라이언트 간의 공유가 이루어 지는 경우인 Client Sharing, 클라이언트, 서버 모두에서 공유가 이루어 지는 경우인 Client-Server Sharing의 네 가지 모델을 분류하였다. 이들의 조합을 통해 총 8가지의 유형을 도출하였다. 또한 각 모델 별로 유형별 구조와 장단점, 인터넷상에서의 지식베이스, Fact Base, 추론엔진 등의 위치 문제와 사용기술, 고려사항, 서비스 유형들을 구분, 분석하였다. 본 논문을 통해서 제시된 프레임워크를 활용하여 새로운 환경에 좀더 능동적으로 대처할 수 있는 효율적인 전문가시스템의 다양한 개발이 기대된다. According to the expansion of the Internet use and the utilization of e-business, there are an increasing number of studies of intelligent‐based systems for the preparation of ubiquitous environment. In addition, expert systems have been developed from Stand Alone types to web‐based Client-Server types, which are now used in various Internet environments. In this paper, we investigated the environment of development for web‐based expert systems, we classified and analyzed them according to type, and suggested general typical models of web‐based expert systems and their architectures. We classified the web‐based expert systems with two perspectives. First, we classified them into the Server Oriented model and Client Oriented model based on the Load Balancing aspect between client and server. Second, based on the degree of knowledge and inference‐sharing, we classified them into the No Sharing model, Server Sharing model, Client Sharing model and Client-Server Sharing model. By combining them we derived eight types of web-based expert systems. We also analyzed the location problems of Knowledge Bases, Fact Bases, and Inference Engines on the Internet, and analyzed the pros & cons, the technologies, the considerations, and the service types for each model. With the framework proposed from this study, we can develop more efficient expert systems in future environments.
