본 연구는 최근 정보업무의 실제영역에서 정보의 부가가치와 정보서비스의 경제성 문제가 점점 중요한 문제로 부각되고 있는 현상을 그 배경으로 한다. 본 연구의 목적은 정보의 가치와 정보의 효율성 측정에 관한 논의를 통해 정보의 경제성 문제를 정보학적 관점에서 재조명하기 위한 것이다. 분석 결과 정보의 부가가치에 관한 논의는 수량화가 어려운 효과적 측면과 관련되며, 효율성 측면에서 바라볼 경우 정보의 경제성 분석은 비용편익 분석과 거의 동일한 개념임을 보여주고 있다. 본 연구는 또한 국립디지털도서관 DLP에 대한사례연구를 통해 정보학의 실제 분야에 적용할 수 있는 경제성 분석의 실험적 모형을 제시하였다.

Mobile telecommunication service is one of the most competitive and rapidly growing industries in Korea. In competitive environments, it is essential to measure and improve customer satisfaction(CS) levels. However, there are a few problems in existing methods of CS measurement. First, sacrifice such as price is not included properly. Thus, the CS is not expanded into the value concept which is important to customer's behavioral intention. Second, CS measurements are not benchmarked with other competitive companies and CS index cannot reflex it properly. AT&T experienced these problems and suggested customer value added (CVA) for CS measurement. In this study, we try to introduce the CVA concept into our mobile telecom services. CS attributes were constructed, an survey was conducted for 5 mobile telecom companies, CS survey results were presented, and the validity of CVA concept was discussed.

This study compares economic impact between Software and Medical industry through Input Output Table by Bank of Korea. We classify Software and Medical industry by The ninth Korea Standard Industry Classification and use linkage effects, value added inducement coefficient, and labor inducement coefficient to analyze economic impact. First, software and medical industry have different linkage effects between backward and forward. Second, They have higher value added inducement coefficient than average of all industry. Third, They not only have higher labor inducement coefficient than average of all industry but also simillar effect on labor induction. According to the result of this study, software and medical industry have high economic impact on Korea economy, and therefore are intensively fostered by policy support.

There is a belief that timely and precise data are important to decisions and the better decisions are related to better firm performance. However, empirical research investigating the effect of data quality on firm financial performance is still scarce up to recently. Current study empirically explores such an effect of data quality on firm accounting performance in the Korean manufacturing industry during 2008~2010 with secondary data. The results show that better data quality does not impact on sales and operating profit, but positively and significantly impacts on EVA(Economic Value Added). Raising the level of data quality management maturity by one level can increase EVA by about 34% in manufacturing firms.

Recently, cloud computing market is growing geometrically in both private and public area, and many global companies in various domains have developed and provided cloud computing services. In such situation, Korean government made multiple plans for domestic cloud computing industry. However, most research institutes have focused on market size and status information, which makes actual effectiveness of cloud computing service hard to recognize. In this study, we define cloud computing Industry by rearranging Input-Output table published by the Bank of Korea to use Input-Output Analysis. The Input-Output Analysis was devised in 1963 by Leontief and it is used in many fields of study until now. It produces various coefficients that are able to identify production-inducing effect, value-added effect, labor-inducing effect, front and rear chain effect. The analysis results show that production-inducing effect, front and rear chain effect of cloud computing industry is low compared to other industries. However, cloud computing Industry possesses relatively high value-added effect and labor-inducing effect. It is because industry magnitude of cloud computing is smaller than other industries such as manufacturing, chemical industries. The economic effects of the cloud computing industry are not remarkable, but this result is significant to emerging markets and industries and presents the fresh way of analyzing cloud computing research field.

Location-based services are a recent concept that integrates a mobile device's location with other information in order to provide added value to a user. Although Location-based Services provide users with comfortable information, it is a complex task to manage and share heterogeneous and numerous data in decentralized environments. In this paper, we propose the Semantic LBS Model as one of the solution to resolve the problem. The Semantic LBS Model is a LBS middleware model that includes an ontology-based data model for LBS POI information and its processing mechanism based on Semantic Web technologies. Our model enables POI information to be described and retrieved over various domain-specific ontologies based on our proposed POIDL ontology. This mechanism provide rich expressiveness, interoperability, flexibility in describing and using information about POls, and it can enhance POI retrieval services.

In developing the ubiquitous computing technology based services (ubiquitous services), evaluating how much value of those services is created or added is very crucial. The efforts to evaluate the ubiquitous services have been progressed in two perspectives - technical perspective and behavioral perspective. Despite its importance, however, the methodologies which integrate both perspectives have been still very rare. Hence, this paper aims perspectives have been still very rare. Hence, this paper aims to propose an integrated ubiquitous service valuation methodology based on the multi-layered approach including technical and behavioral perspectives. To do so, we conducted a case study with currently existing location based service (LBS) such as navigation systems by conducting focus group interview (FGI) and field survey.

Location Based Services, or LBS refers to value-added service by processing information utilizing mobile user location. With the rapidly increasing wireless internet subscribers and world LBS market, the various location based applications are introduced such as buddy finder, proximity and security services. As the killer application of the wireless internet, the LBS has preconsidered technology about location determination technology, LBS middleware server for various application, and diverse contents processing technology. This paper describes the open architecture for LBS platform ensuring interoperability among the wireless networks and various location-based application services and the functional requirements for the LBS platform. The LBS platform in a narrow sense provides a standard interfaces for location management and network management for location services as follows, positioning (location acquisition through network or/and handset), location managing, location based functions, profile management, authentication and security, location based billing, information roaming between carriers and the system monitoring independent to specific network or ISP/CPs(Content Providers).

본 연구는 국내 재배면적이 확대되고 있는 목이버섯의 부가가치 향상과 소비량 확대를 위해 팽화기술을 접목한 목이버섯 즉석죽을 제조하고, 품질특성을 조사하여 실버층에 쉽게 적용할 수 있는 제품을 개발하고자 하였다. 백미와 흑미를 75~100%와 25~0%로 혼합한 후 비타민 $D_2$와 식이섬유 함량이 높은 건목이버섯을 0~4%로 첨가하여 호화도, 영양성분, 항산화성 및 관능 등을 조사하였다. 즉석죽 분말의 호화도는 건목이버섯 첨가량이 증가할수록, 흑미 첨가량이 감소할수록 최고점도와 유지강도, 강하점도, 최종점도, 노화점도가 증가하는 경향이었다. 백미 80%와 흑미 20%를 혼합한 후 건목이 버섯 3%를 첨가한 즉석죽은 비타민 $D_2$ $18.53{\mu}g/100g$, 식이섬유 3.73 g/100 g이 함유되어 있어 뼈의 형성과 유지와 배변 활동 촉진 효과가 기대되었다. 또한 DPPH free radical 소거능도 56.79%로 나타나, 항산화성이 높아 실버층의 건강에 기여할 것으로 기대되었다. 본 실험 결과, 목이버섯은 기능성 가공제품 개발의 소재로서 사용가치가 매우 높아 실버층뿐 아니라, 다양한 연령층에 적합한 가공제품 생산에 응용가능하리라 생각된다.

The proposed system measures business performance by considering both VA(Value-Added), which represents stakeholder's point of view and EVA(Economic Value-Added), which represents shareholder's point of view. To do so, we suggest a business performance scheme which utilizes VA per Capita (Value- Added/Workers) and EVA to Invested Capital(Economic Value-Added /Invested Capital). For effective measurement of business performance, we consider simultaneously not only quantitative financial factors such as VA, EVA and cash flow but also qualitative value drivers such as defect ratio, inventory level, customer satisfaction, enterprise culture and so on. However, we don't consider the qualitative factors due to the limited data. To demonstrate the performance of the system, we conducted a case study using financial data of Korean automobile industry over 16 years from 1981 to 1996, which is taken from database of KISFAS (Korea Investors Services Financial Analysis System).
