This study aim to analyze the effect of the technology support program satisfaction on below ICT Small and Medium-sized Enterprises(below SMEs)'s technological performance. For the empirical analysis, we used the data collected from ICT SMEs technology support program conducted by ETRI - a government funded research institute. Among 153 beneficiaries, 141 companies participated in the survey and we used 102 of them for our analysis. Then, we used the mediation regression analysis. In our research model, we set the program satisfaction as a independent variable, the amount of technology support as a mediator variable and the technological performance as a dependent variable. Results show that program satisfaction has positive and significant impact on both amount of technology support and technological performance and amount of technology support has complete mediation effect on product innovation while has partial mediation effect on technological innovation. Our findings imply that more ICT SMEs technology support programs that satisfying the beneficiaries should be developed until the rest of ICT SMEs could become the hidden champions.

Managers of firms often wonder whether advertising expenditure is a mere expense or an investment with foreseeable future returns. When top management makes a decision on the level of advertising expense, it must consider whether an increase in advertising spending will positively affect brand loyalty and the increased brand loyalty will positively affect profitability and firm value. We investigate the industry-specific effects of advertising spending on marketing and the effect of loyalty on financial performances using top companies in Korea, specifically, 184 firms' data from year 1998 to 2014. The empirical results of a fixed effect model indicate that the effects of advertising on customer satisfaction index and loyalty on the firms' financial performance are positive. In service industry, unlike manufacturing industry, advertising has a significantly positive effect Brand Loyalty. In addition, Brand Loyalty had positive impacts on ROA and ROE as profitability index, and Tobin's q, a market-value index. The research results suggest that advertising in service industry should be considered as customer satisfaction investment and the increased Brand Loyalty as a profit for present and a business investment for the future respectively.

Recently, social network service (SNS) is actively used by public. Among them, Twitter has a lot of tweets including sentiment and it is convenient to collect data through open Aplication Programming Interface (API). In this paper, we analyze social issues and suggest the possibility of using them in marketing through sentimental information of users. In this paper, we collect twitter text about social issues and classify as positive or negative by sentiment classifier to provide qualitative analysis. We provide a quantitative analysis by analyzing the correlation between the number of like and retweet of each tweet. As a result of the qualitative analysis, we suggest solutions to attract the interest of the public or consumers. As a result of the quantitative analysis, we conclude that the positive tweet should be brief to attract the users' attention on the Twitter. As future work, we will continue to analyze various social issues.

Corporate Culture Marketing is a marketing tool that enhances a company's cultural image or conveys its image through culture. Culture Consumer value analysis is important predictive data in identifying the value and pursuit of life in individual consumption behavior, explaining the choice behavior of culture consumers, and serves as the basis for decision making. The research method was linked to the text mining and opinion mining techniques of big data, and extracted positive, negative and neutral words. The analysis targets culture consumers participating in concerts at Hyundai Card's 'Super Concert', which is subject to domestic consumers, and CJ ENM's 'KCON', which is subject to foreign consumers. The culture consumer value elements of corporate culture marketing are the basic conditions, and they were derived as 'Consensus Communication (Expression of Sensibility)', 'Participation Sharing(VIP Belonging)', 'Social Change Issue', 'Differentiating Services', 'Price Discount Benefit' and 'Location Quality'. In the future, we will need to foster 'Culture Technology Marketers' and apply them in areas such as arts management planning, cultural investment, cultural distribution, cultural space, Corporate Culture, CSR and K-pop marketing to enhance corporate interests and brand value and enhance brand value.

This paper analyzes the efficiency of Korean Financial Investment Institution using DEA model. We evaluate the CCR, BCC efficiency and RTS of 30 Financial Investment Institution. We also suggest the Financial Investment Institution which can be benchmarked based on analyzed information. The result shows that 3 Institution whose values of CCR efficiency are 1, and 7 Institution whose values of BCC efficiency are 1. RTS indicates IRS of 21 Investments, DRS of 6 Investments and CRS of 3 Investments.

This study analyzes the relationship between R&D input and performance using panel data from the defense industry. A research model is established based on the R&D logic model, and the study sample consists of a strongly balanced panel data (n=351) empirically analyzed using panel linear regression. Results identified that defense improvement expenditure has a positive influence on the R&D input, and R&D input positively affected patents using a 5-year time lag. In addition, R&D input positively impacts economic performance, including sales and profit. Hence, the major finding includes R&D inputs have statistically significant effects on economic outcome and the R&D logic model featuring a time-lag.

정보통신기술의 급속한 발전으로 인해 인터넷은 사회 전분야를 변화시키고 있으며 다양하고 폭넓은 이용 행태에 따라 지금 이 순간에도 엄청난 데이터를 생산해 내고 있다. 대부분의 인터넷 데이터는 제한적인 활용 이외 단순 생성과 소멸을 반복해 왔으나 최근 들어 빅데이터(Big Data)라는 핵심 키워드의 부상으로 인터넷 데이터에 대한 관심이 고조되고 있다. 과거에도 데이터 마이닝(Data Mining), 비즈니스 인텔리전스(Business Intelligence), 라이프 로그(Life Log) 등을 통해 데이터 기반의 부가가치를 창출하려는 노력은 시도되어 왔다. 그렇다면 왜 다시 빅데이터라는 이름으로 재부상 하고 있는 것일까? 이는 정보통신기술의 진화와 맞물려 새롭게 부상하고 있는 인터넷 글로벌 기업들이 지속적으로 생성되는 다양한 데이터들을 확보하고 그 속에서 숨겨진 가치를 찾고 인사이트(Insight)를 도출하려는 시도를 통해 데이터 보유와 활용이 새로운 경쟁력이 될 수 있음을 입증하고 있기 때문이다. 이러한 시도들은 빅데이터를 다양한 분야에서 중요한 이슈로 자리매김하게 하고 있다. 이러한 상황에서 과연 우리는 빅데이터 시대를 어떻게 리드하고 무엇에 집중하여야 할 것인가? 본 연구는 현재 뜨거운 감자로 부상한 빅데이터를 정의하고 빅데이터 시장분석, 사례분석, 정책분석을 통해 시사점을 도출하여 향후 다가올 빅데이터 시대의 국가경쟁력 확보를 위한 빅데이터 이니셔티브(Initiative)의 필요성과 중점 방향 등을 제언하고자 한다.

This study analyzes the technological level of Korean waste-to-energy(WTE) firms and its determinants by using a multiple logistic regression analysis based on a survey. As the results of analysis, the technological level of Korean WTE firms has been positively influenced by the firm size, R&D expenditures, R&D manpower, but negatively influenced by the competition in domestic market. Also there is no significant effect of the economy of scale. The policy implications of this study are as follows; First, the system in which stakeholders coevolve should be set up to prevent excessive market competition from having a bad effect on the technological level of Korean WTE firms. Second, it is needed to make an effort to achieve the economy of scale by increasing an output and decreasing cost in WTE firms.
