This case study quantifies the savings that can be realized through integration in National Computing & Information Agency (NCIA) of the Korea Government. It is based on the process of the NCIA development project that consolidating and integrating distributed 24 agencies. And it used the widely accepted Gartner TCO (Total Cost of Ownership) Solution and applies that methodology consistently before and after integration. Specific measurement items for examining the information system integration saving cost are developed pilot test for 2 agencies through compare TCO before integration and TCO after integration. The results of measuring on information system integration in NCIA are showed lots of economic cost reduction in TCO by integrating and consolidating each computing environment in agency. Especially in detail, NCIA realized the most savings in IT Capital Cost including development of hardware, software and recovery system. Also IT Support Cost and IT Administration Cost examined more savings than before IT integration.

The purpose of this study is to investigate the impact of win-win growth activity of domestic large firms on their management performance. we classified the management performance into four factors such as ROE(Return On Equity), ROA(Return On Assets), net income to net sales and operating income to sales. The finding of this study is outlined as follows. This paper show that the win-win growth activity has a negative impact on the firms' management performance. This study shows that win-win growth activity could generate additional costs of business activity. So, we think that industrial policy is needed for expansion of win-win growth activity.

This study analyzed to provide information for business improvement by analyzing the management efficiency of start-up investment companies so that startup investment companies can operate efficiently and by presenting information on inefficient factors. From 2014 to 2018, 83 start-up investment companies were analyzed using the DEA model. Input variables were he number of employees, capital, and output variables were selected for start-up investment assets, operating income, and net profit. As a result of the analysis, technical efficiency and pure technical efficiency showed a pattern with an increase in average, but scale efficiency repeatedly increased and decreased. It is believed that the decline in technology efficiency was due to the decrease in pure technology efficiency, and the inefficiency of start-up investment companies seems to have influenced the inefficiency of start-up investment companies rather than the inefficiency of scale. In addition, the size revenue shows that the DRS value is gradually decreasing, and the IRS value is generally increasing. It is believed that efficiency can be improved if operational inefficiency is improved based on the results and efficiency measures are established through scale expansion.

The study divided the life cycle of Chinese companies into three stages from 2011 to 2017, 3,750 small and medium-sized enterprises(SME) used disclosure data to analyze the intensity of R&D investment by company life cycle. The analysis showed that the impact of wealth(ROA) on the performance of R&D investment(RDS) and the next(t) business performance, and research and development investments had a different impact on the company's performance depending on the life cycle of the company. The results of this study are expected to help determine the amount of expenditure related to R&D investment and the time of input of resources in consideration of industrial characteristics and corporate characteristics when making strategic decisions related to R&D investment of companies.

The purpose of this study is to identify the CSR activities and to investigate the relationship between CSR activities and business performance. Specifically, we analyzed the companies that were included in the SRI index as CSR activity companies, and analyzed how they affect the business performance of the companies according to SRI index incorporation disclosure. As a result of the analysis, the SRI index incorporation announcement has a significant positive effect on the corporate value(Tobin's Q) but it has not significant effect on the financial performance(ROA). This suggests that CSR activities are offered to companies' managers and stakeholders as a basis for investment rather than expense. In the future research, it will be more meaningful if the study on the intention to participate in CSR activities is conducted based on this study and previous studies.

Modern naval ships install an Infra-Red Signature Suppression system (IRSS) in their exhaust pipe to reduce infrared signature emitted to the outside. In addition, naval ships are strategic assets with a very long life cycle, so high reliability of the performance of the equipment on board must be guaranteed. Therefore, equipment such as IRSS is evaluated for performance through model testing at the design stage. A variety of measuring instruments are used in IRSS model testing, and the reliability of these instruments must also be guaranteed. In this paper, a study was conducted to evaluate the reliability of measurement equipment used in IRSS model testing. The test equipment and instruments used were a hot gas wind tunnel, pitot tube, digital differential pressure gauge, thermocouple sensor, and digital recorder. As the fan speed of the hot gas wind tunnel increased, the measurement deviation of the flow decreased, and the temperature output of the thermocouple sensor showed differences in response time and stability depending on the method used.

This study conducted a quantitative research on the artistic perception and acceptance of value among buyers of commodified digital art known as NFT artworks. NFTs, digital assets, have shown rapid growth as investment products, but recently there has been a trend of declining value. However, NFT art, characterized by uniqueness and scarcity, continues to undergo continuous development to create new opportunities and values. Nonetheless, there are also negative opinions regarding NFT art itself as a form of technological art, as well as concerns about copyright disputes and fears of a bubble due to the conversion of physical artworks into NFTs. Predicting the value of artworks targeting specific demographics is difficult, and the value of innovative art such as NFT art, which changes along with the fluctuation of cryptocurrency values, is even more challenging to predict. Therefore, through research on the buyers who play a crucial role in the growth and development of this new form of art, the study aims to contribute to the expansion of NFT art.

There are many famous, well-known special collections built with unique and valuable materials in the libraries all around the world. These special collections are very important for the public and especially for the researchers. Digital access and the Web have altered the landscape of special collections and allowed increasing numbers of users to locate and access rare and valuable materials of special collections. This change has also affected libraries with the responsibility of building and managing special collections. The goal of this paper is to provide readers with insight into the culture of the special collection and to suggest good ideas for public libraries to build their special collections by introducing the special collection building cases in USA and Korea through investigating the public library websites.

국내의 원격검침 데이터는 주로 전력요금 산출용도에 활용되고 있다. 하지만 국외 전력회사들은 미래 디지털 사회의 기반이 되는 신 전력시스템을 구현하는데 필요한 핵심기술 중의 하나로서 IT(Information Technology)기반 전력부가서비스 기술의 중요성에 대해 강조하고 있으며, 이를 위해 원격검침 데이터를 기반으로 하는 다양한 전력부가서비스를 개발하여 적용하고 있다. 따라서, 국내의 경우도 원격검침 데이터를 단순한 전력요금 산출용도가 아닌 전력소비자와의 관계에서 부가가치를 높일 수 있는 무한한 잠재력을 지닌 전략적인 자산으로 보고, 원격검침 데이터 가공 및 활용기술의 선진화를 통하여 전력회사와 전력소비자 모두에게 필요한 전력부가서비스의 적용이 필요하다. 본 논문에서는 국내외 전력부가서비스 시스템의 비교 분석을 통해 국내 전력산업 환경에 적합한 새로운 전력 부가서비스 적용방향을 제시하고, 이를 기초로 설계한 전력부가서비스의 일종인 전력 에너지 컨설팅 서비스 시스템에 대해 소개하고자 한다. 설계한 전력부가서비스 시스템의 적용시 전력소비자 측면에서는 요금절감 효과가 전력회사 측면에서는 부하 수요관리 및 투자비 절감 효과가 예상된다.

Recently, the comparative gap of technology and product has been decreased in the global market, and the globalization has been extended rapidly. Industries try to get de facto standard as the global standard. De facto standard has become a standard not because it has been approved by a standards organization but because it is widely used and recognized by the industry as being standard. Advanced countries already have their own organizations under the government, and they cooperate tightly with companies. As a result, we also try to have the organization and build the good relationship between companies and the government to get de facto standard in the global market.
