본 논문은 한국 정보통신산업의 생산성 변화를 분석하고 시사점을 도출한다. 분석방법은 11개의 한국 정보통신산업의 횡단면자료와 8개년의 시계열 데이터를 이용한 패널분석이다. 분석 결과로 전 기간에 걸쳐서 정보통신산업의 노동생산성과 자본생산성, 그리고 총요소생산성은 정(+)의 부호를 나타냈다. 정보통신산업 생산성의 변화는 먼저 총요소생산성은 2008년 이후 감소한 것으로 나타나 기술수준과 경영수준의 향상이 없었던 것으로 판단된다. 그리고 노동생산성은 증가했지만 자본생산성은 감소한 것으로 나타났다. 특히 자본생산성의 감소가 폭이 상대적으로 크다. 이러한 결과는 그동안 한국경제의 주력산업으로서 정보통신산업에 대한 양적투자의 증가에 의한 성장에도 불구하고 생산성이 개선되지 못하여 정보통신산업의 근본적인 경쟁력의 향상이 이루어지지 않았음을 의미한다.

정부는 SW 중심사회 실현을 위해 SW 산업에 대한 정책역량을 집중해 왔으며, 이를 통해 SW 산업은 지속적인 발전을 거듭하고 다양한 산업들과의 융합을 통해 고부가가치 산업으로서 그 중요성과 시장이 폭발적으로 확대되고 있다. 그러나 소프트웨어 산업에 치중된 급격한 지원 정책들로 인해 사업자 선정 혼란에 따른 시공품질 저하, 업역(시장)분쟁 등 다양한 문제와 부작용이 발생하고 있다. 따라서 본 논문에서는 급속한 시장 변화에 따른 소프트웨어 지원 정책 및 관련 법령들에 대한 문제점과 관련 원인을 파악하고 그에 따른 개선안을 제안함으로써, 복합적 ICT 산업의업역 명확화(소프트웨어 및 정보통신공사업)를 통해 사업자 선정 혼란에 따른 문제점들을 최소화하고자 한다.

This study was fulfilled in the purpose of proposing construction strategies of fashion information industry through the analysis of information user's satisfaction/dissatisfaction on information quality. The research was performed through a depth interview. Data were collected from 18 fashion information users(designers and merchandisers) who were working at fashion apparel industry during October to November 2007. Results from the study showed that there were three dimensions and 18 components of satisfaction/dissatisfaction on fashion information quality: Information quality(understandability, value-added, level of detail, relevance, diversity, objectivity, completeness, accuracy, quantitativeness), Service quality(responsiveness, accessibility, cost efficiency, empathy, reliability), System quality(currency, ease of use, format, timeliness). And the information users were perceiving that there were some changes in notion of preferring information, searching for information and usage of information.

In this study, we proposed the social map system prototype for intelligent crime prevention. For developing the social map system prototype, functional requirements were derived through the analysis of related cases and preceding studies. Derived requirements are providing a variety of map-based safety information, using crowdsourcing data such as SNS, connecting to intelligent CCTV. To satisfy these requirements, the prototype is developed with four main menus: the integrated search menu including social media data, the safety map menu providing a variety of safety and danger information, the community map menu to collect safety and danger information from users, and the CCTV menu providing the link to intelligent CCTV. The social map for intelligent crime prevention in this study is expected to greatly enhance the safety of local community with the provision of prompt response to risk information, safe route, etc. through actual service and user participation.

In these days the global software market is experiencing diastrophism due to globalization, convergence, and the spread of web 2.0. In particular, today"s global economy has entered the so-called "Globalization 3.0" era, and the world is evolving into a flat world where labor, capital, and resources are moving freely. In this rapidly changing global economy, the growth of the Korean economy is in a state of continuous decline. Particularly software industry is also suffering continuously slow growth due to market saturation and low service earning, which require urgent countermeasures. Therefore, the purpose of this study is: 1) to analyze the current industrial condition of the software industry, which have special characteristics differ from manufacturing industry; and 2) to analyze the major obstacles of local companies working in the software industry in order to cope with the recent changes in the global market environment and 3) to draw out the strategy for the domestic software industry in gangwon province in order to promote local software industry and to achieve globalization.

Based on reviewing the literature and statistical year books on current projects that are targeting Industry 4.0 and Smart Factory, this paper aims to show concepts of Industry 4.0, and Smart Factory. Also it shows 5 projects for Industry 4.0 led by governments that worry over their low employment and productivity in main industrialized countries: Germany, China, Japan, the USA, and Korea. In addition it presents some problems which are very important but easy to be overlooked, especially on employment, and it makes three suggestions to solve employment problems. First, government should tax the profit which a company makes on reducing workers in spite of a high rate of profit through technology innovation. Second, to help small businesses to last longer, government should link major companies and small companies. Third, government, academic circles and the industrial world should take part in configuring consortia like American "Industry talent Consortium" to cultivate IT Talent.

The purpose of this paper is to shed light on the current status of Industry 4.0 policies in India and provide holistic policy recommendations in the transition towards Industry 4.0. The study was conducted based on the content-centric review of written policy documents like policy memoranda (memos), green papers and white papers, policy briefs, policy reports, opinion pieces, and newspaper and academic publications on Industry 4.0. India lacks infrastructure, regulatory framework, architectural reference model, incentives, skills, and standard roadmap towards Industry 4.0. The current policy status and policy recommendations presented in this study can serve as a great asset for academicians, policymakers, and practitioners to prepare a holistic roadmap for Industry 4.0 policy implementation. The study is first to assess India's current policy status and compare with Germany towards Industry 4.0. Besides, it is expected to assist government policymakers in formulating tangible policy outputs and strategic roadmaps.

According to information theory, non-orthogonal transmission can achieve the multiple-user channel capacity with an onion-peeling like successive interference cancellation (SIC) based detection followed by a capacity approaching channel code. However, in multiple antenna system, due to the unideal characteristic of the SIC detector, the residual interference propagated to the next detection stage will significantly degrade the detection performance of spatial data layers. To overcome this problem, we proposed a modified power-domain non-orthogonal multiple access (P-NOMA) scheme joint designed with space-time coding for multiple input multiple output (MIMO) NOMA system. First, with proper power allocation for each user, inter-user signals can be separated from each other for NOMA detection. Second, a well-designed quasi-orthogonal space-time block code (QO-STBC) was employed to facilitate the SIC-based MIMO detection of spatial data layers within each user. Last, we proposed an optimization algorithm to assign channel coding rates to balance the bit error rate (BER) performance of those spatial data layers for each user. Link-level performance simulation results demonstrate that the proposed time-space-power domain joint transmission scheme performs better than the traditional P-NOMA scheme. Furthermore, the proposed algorithm is of low complexity and easy to implement.

Owing to the change of economic trends, the importance of the tourism industry is growing more and more. In particular, the number of foreign tourists continues to increase and the type of tourists is being changed into FIT (Foreign Independent Traveler). Therefore it is an important issue to provide the effective information to foreign tourists. To solve these problems, a variety of IT technology is being used in the tourism information systems. Especially the location based tour information service is being emerged. This kinds of tourism information service is a type of LBS (Location Based Services). But if the security of the location based tourism information service is not guaranteed, it can lead to many dangers. In this paper, the trends of location based tourism information service are surveyed. Also the security threats and countermeasures for the location based tourism information service are analyzed. This paper suggests secret considerations for the location based tourism information service.
