The purpose of this study is to elaborate the underlying mechanism by which information competency of those with disabilities influences their level of life satisfaction through a mediator, social capital built up through online and offline activities. To this end, the research conducts mediation analysis, comprised of three sets of regression by using the data of the "2018 Report on the Digital Divide." The results demonstrate that the information competency of those with disabilities has a significant effect on their level of life satisfaction; the higher the information competency, the greater the social capital. In addition, social capital partially mediates the relationship between information competency and life satisfaction. The policy implications from this study indicate that the efforts to improve information competency of those with disabilities should be made in a way that facilitates social interactions and community participation.

Forcasting the future is a very important task in design situation analysis. To do this, the reduction of life style, the tendency of product differentiation and individuality should be considered along with such changes as cultural, economical and social trends. At the moment, industrial structure is being reorganized from centering around the manufacturing industry to the distribution industry and consumers. Consumers show the attitude of expressing their individualities on the basis of various tastes rather than standardization. The flow of information also has been changing rapidly from the former types of information provided by producers to the age when consumers pursue the objective and model of information. Therefore, we are able to say that picking up the trends around the streets becomes more important than ever. Accordingly, the objective of this study is to establish a system which is able to effectively carry out the trend analysis by a town watching method, the construction of a database with collected data, and its practical application on the web.

This paper presents the new methodology of analyzing and classifying patterns of customers in mobile telecommunication market to enhance the performance of predicting the credit information based on the decision tree and neural network. With the application of variance selection process from decision tree, the systemic process of defining input vector's value and the rule generation were developed. In point of customer management, this research analyzes current customers and produces the patterns of them so that the company can maintain good customer relationship and makes special management on the customer who has huh potential of getting out of contract in advance. The real implementation of proposed method shows that the predicted accuracy is higher than existing methods such as decision tree(CART, C4.5), regression, neural network and combined model(CART and NN).

In order to respond quickly to security threats that are increasing fast and variously, security control personnel needs to understand the threat of a massive amount of logs generated from security devices such as firewalls and IDS. However, due to the limitations of the information processing capability of humans, it takes a lot of time to analyze the vast amount of security logs. As a result, there is problem that the detection and response of security threats are delayed. Visualization technique is an effective way to solve this problem. This paper visualizes the security log using the RGB Palette, offering a quick and effective way to know whether the security threat is occurred. And it was applied empirically in VAST Challenge 2012 dataset.

수송용 산업의 하나인 국내 조선업계는 2008년 말 이후 세계 조선경기 불황 속에서도 2009년 451억달러, 2010년 491억달러의 사상최대 수출액을 달성한 바가 있고 세계 조선사 순위에서는 1위에서 5위까지 한국 조선소 등이 우위를 차지하고 있다. 그러나 개별 기업 경쟁력은 우위에 서있지만 중국과의 격차가 많이 좁혀지고 있어 안심할 수 없는 상황이다. 특히 최근에는 탄소배출량이 적은 친환경 선박의 제조가 선박업계 전반의 화두로 대두되고 있다. 이를 위해 다양한 시도가 시도되고 있는데 그중에 하나가 선박의 경량화이다. 금속외장 전선은 선박 무게의 10~13%를 차지하고 있고 전체 사용 전선의 30~40%를 차지하고 있어 선박에서의 금속외장 전선의 무게를 줄이기 위한 연구가 필요한 실정이다. 또한 조선산업 뿐만 아니라 자동차 분야에서도 금속 외장전선이 많이 사용되고 있으며, 자동차의 연비 향상을 위한 경량화 연구가 더욱 절실한 상황이다. 본 연구에서는 수송용으로 사용되는 전선의 금속외장을 경량 고강도 섬유를 활용한 하이브리드 wire로 대체하기 위한 편조 기술 및 편조 장치를 개발하기 위한 설계 및 기초연구를 수행하였다. 초경량 고강도 섬유 Armor의 제조기술 및 최적 공정 개발을 위한 연구로서 경쟁사 샘플에 대한 분석을 실시하였고, 사용된 섬유의 성분 분석 및 물성시험을 수행하였다. 또한 원형직기 개발을 위한 구조부 설계를 위해 ANSYS해석을 수행하고 저신율 고강도인 아라미드의 이징모션 시스템 개발을 위한 연구를 수행하였으며 개구 형성방법을 설계하였다. 그리고 초경량 고강도 hybrid 케이블 아라미드 편조 표면 및 내부 가교에 의한 가공 기술을 연구하였다. 아라미드 섬유의 발수성 향상을 위한 코팅재료 선정을 위한 연구를 수행하였고, 자외선 경화공정에서 조건별 데이터를 정립하여 솔루션을 제공하고자 한다.

As the AI speaker market is growing rapidly in recent years, the competition for the preoccupation of children who are the main users and the future prospective customers of the related companies is very intense. However, there is a lack of empirical research on how children interact with AI speakers. Therefore, this research examines the interactions between children and AI speakers, primarily through field studies, to extract what functions they use and what features they have. For this purpose, 799 conversations were collected and analyzed using the log data of the AI speaker recorded in real time. As a result, children were more likely to use children's songs, fairy tales, emotional conversations, and personification compared to adults. In addition, content analysis by specific types resulted in success/failure cases of interaction between children and AI speakers and proposed improvements by failure type. This study is meaningful in that it identifies children's AI speaker preferences, content, and major conversation patterns, and provides guidelines for developing services that meet children's eye level.

The purpose of this study was to analyze the mediating effect of work environment and the moderating effect of gender on the influence of interpersonal relationship of fusion integrated generation of youths on organizational commitment. For this purpose, Korean Labor and Income Panel Study KLIPS 19th year data was used and the effect of interpersonal relationship of youths on the organizational commitment of 540 subjects in accordance with the study was examined and explored focusing on the model in relation to the mediating effects of the work environment and the control effects of gender. The main results are as follows. First, the interpersonal relationship and working environment of youths showed a positive effect on organizational commitment. Second, the working environment was found to be mediated completely in the relationship between the interpersonal relationship of youths and work environment and organizational commitment. Third, in the relationship between interpersonal relationship and organizational commitment of youths, it appeared that there was moderating effects of gender.

This study investigated the antecedents of VR(virtual reality) headsets acceptance and the causal relationships among self-efficacy, content diversity, the perceived usefulness, the perceived easy of use, the perceived playfulness and the adoption intention. We collected 238 survey responses and formed structural equation modeling with AMOS 23.0. The results of the analysis can be summarized as follows. The diversity of contents and self-efficacy had significant effects on perceived usefulness, perceived ease of use and perceived enjoyment, thus increasing the intention of acceptance. Perceived usefulness, perceived ease of use and perceived enjoyment had significant effects on the intention of acceptance. Perceived ease of use indirectly had an effect through increasing perceived enjoyment. The price did not affect the adoption intention and marketing communication increased the intention of acceptance. The results are expected to provide useful information to the companies related to VR.

The purpose of this paper is to analyze the Japanese emission trading system and climate change policy thereby contributing to the instituting of similar systems that will be viable for the Korean context. In applying such analyses, it is important to include a careful consideration of cost sharing between stakeholders and firms, an enhancement of the trust worthiness of data concerning greenhouse gases, and an examination of related infrastructure such as emissions authentication agencies and their development. Moreover, it is important to minimize the outflow of domestic resources such as offset credit, green electricity certification system, and ecopoint, making compatible economic growth and carbon reduction thereby encouraging the production and dissemination of 'Environmental Value' as well as connecting 'Environmental Value' to a emission trading system.
