Recently, web search query information has been applied in advanced predictive model research. Google dominates the global web search market in the Korean market; however, Naver possesses a dominant market share. Based on this characteristic, this study intends to compare the utility of the Korean web search query information of Google and Naver using predictive models. Therefore, this study develops three time-series predictive models to estimate the youth unemployment rate in Korea using the ARIMA model. Model 1 only used the youth unemployment rate in Korea, whereas Models 2 and 3 added the Korean web search query information of Naver and Google, respectively, to Model 1. Compared to the predictability of the models during the training period, Models 2 and 3 showed better fit compared with Model 1. Models 2 and 3 correlated different query information. During predictive periods 1 (continuous with the training period) and 2 (discontinuous with the training period), Model 3 showed the best performance. During predictive period 2, only Model 3 exhibited a significant prediction result. This comparative study contributes to a general understanding of the usefulness of Korean web query information using the Naver and Google search engines.

The purposes of this study are to examine the correlations among mental health and quality of life in stroke patients and find the factors affecting quality of life. The participants were 224 inpatients diagnosed with stroke. The Stroke Specific Quality of Life(SS-QOL) was used for measuring Quality of life and the Symptom Check-List-90-Revised(SCL-90-R) was utilized to measure mental health. The relationships among the variables were examined with Pearson correlation coefficients. And the simple regression analysis and stepwise multiple regression analysis were performed to identify the predictive variables that explain changes of quality of life. There were statistically significant correlations between quality of life and mental health. Mental health was identified as a factor that explains 28% of change in quality of life. And depression was identified as a factor that explains 42% of change in quality of life. The quality of life in stroke patients, the depression was negatively related with it. When working with a stroke patient, an occupational therapist needs to address mental health aspects from the beginning of the rehabilitation process for a holistic approach and optimal outcome.

Recently, as GIS industry has substantially grown up, convergence between industries such as the application coverage of surveying and cadastral information is gradually on the increase. The new approach of convergence between topographic surveying and cadastral survey is indispensable to make the change of geospatial environment ready and to maximize the utilization of National Spatial Data Infrastructure(NSDI). The purpose of this paper is to seek the way of synergistic improvement in topographic surveying and cadastral survey in comprehensive aspects of national geospatial information. First, we reviewed policy environment to clearly establish aim of convergence and promising perspective of GIS industry policy, considering NSDI. In addition, we examined current state of administration (organization, human resource, service) and institution situation. We came up with interior ability and external policy environment as well as critical success factor for the synergistic convergence by using SWOT analysis. Lastly, we developed basic perspective of convergence and improvement model and concrete scheme for stakeholder to complementary make progress. We can come to conclusion that the convergence of topographic surveying and cadastral survey should be not only carried in macro outline of successful NSDI but also committed to completion and maintenance of GIS framework.

Recently, the value and the status of the digital archives that are built individually in the crossroads of oblivion and memory are due to big data has attracted attention globally is confusing. Video data that contains the cultural memory of the digital archive, such as culture, art, life, society, and social conditions of the time, it is a cultural heritage of national common expressed. Also, it remains a trace of history from the various media just like magazines, books, painting, photography, and film. Digital archive system is one of the best research results of media convergence and it has also a good opportunity to take full advantage of the new opportunities and cultural assets. The collection of infinite information of big data in perspective transient that exist at the same time compatibility of big data, it is trying to dismantle the cultural memory of us. It was asserted that must meet the criteria which can correspond to via the new digital era, will be applied to preserve the traditional media. The current image archive is necessary to accommodate proper two different directions.

This study analyzed through GEM-listed companies for verifying the interrelationship between positive and negative impacts on accounting information GEM-listed companies, whether venture firms operate the internal control operation system stably. Hong Kong's GEM listed company is a securities market similar to Korea's KOSDAQ market. To analyzing this study, used regression analysis method through internal control index to evaluate the operation of internal control system and discretionary accruals to evaluate the quality of accounting information. In this study, because profit adjustments used to realize through discretionary accruals, so analyzed using the modified Jones model to check whether the management deliberately transformed the company to realize future profits. In the empirical analysis, the correlation between the internal control index and the discretionary accruals to assess the quality of accounting information was able to find highly correlated. This study can provide useful guidance for evaluating the form and value of profit management of venture firms in the future, also would expect to help understand the financial environment of emerging venture firms.

Mobile phone-related industries have been mainly concentrated on attracting the new customers and increasing the market share such as for the aggressive marketing activities, but it is the time to find an effective strategy to preserve existing customers since the mobile phone market had already reached the saturation. In this study, the properties of mobile phone that influence on the choice of handset and telecom company were analyzed. General properties of respondents were explored and the mobile phone properties were grouped by common factors. And analyzed the effect of factors on customer satisfaction with structural equation model. 10.4% of respondents are used their handset more than two years and 48.7% wanted to purchase other manufacturer's handset if they repurchase mobile phone. These results might come form the fact that the life cycle of mobile phone become shorter by the heating competition in mobile phone market and, to some degree, the influence of smart phone which recently become globally popular. Four factors, 'Hardware Quality', 'Practicality', 'Convergence Functions' and 'Level of Awareness', are induced from the mobile phone properties. In Structural Equation Model analysis, 'Hardware Quality' and 'Practicality' have significant and positive effects on Customer Satisfaction. But, 'Awareness' such as brand and trend appeared quite less influence on the customer satisfaction.

With an increase in urban crimes in various forms, this study is intended to analyze the effectiveness of the service design that presented a new model resolving crime risks through differentiated thinking paradigm and problem approaches. The empirical case addressed in this study is 'the project to create resident-driven safe community in Duryu-dong, Dalseo-gu, Deagu though service design'. This project is evaluated as having prepared a prevention-oriented local safety system through a preemptive and resident-centered process. The project was promoted as a 'natural monitoring capacity building program' for residents to prevent local crimes, a 'social role expansion program' for local safety, and 'crime prevention environment design', which provides comprehensive solutions for residents' safety. Here, designers act as exerts in designing a task-based platform that can be driven by residents rather than a visual environment improver, and reorganizing the local ecosystem by expanding the opportunities for residents to interact. This case identifies the role of service design as binding the solidarity of local residents beyond the improvement of the crime environment and giving them the potential capacity to maintain a safe living space in relation to a safety issues of community.

Due to the limitations of public and private blockchain, several organizations are implementing consortium blockchain systems. In order for an organization to conduct business using blockchain, it must consider 'blockchain governance' factors, such as decision rights, accountability and incentives over on-chain and off-chain, depending on the organization's strategy and objectives. If an organization conducts business without blockchain governance, it cannot achieve its strategy and objectives systematically, effectively and efficiently, and cannot comply with internal external requirements such as the expectations of stakeholders and laws. However, as businesses using consortium blockchain expand, there is no research on consortium blockchain governance. Thus, in this study, the consortium blockchain governance framework, including functions, roles and responsibilities, was developed to help organizations effectively and efficiently conduct business using consortium blockchain. In addition, to review the feasibility of the developed consortium blockchain governance framework, the framework was reviewed through an advisory committee consisting of experts on blockchain and governance over two occasions. As a result of the review, components of the consortium blockchain governance framework, including functions, roles and responsibilities, were considered complete and relevant.
