This paper offers new ways to learn about popular places in the city. Using locational data from Social Media platforms platforms, including Twitter, Facebook, and Instagram, along with participatory field visits and combining insights from architecture and urban design literature, this study reveals popular socio-spatial clusters in the City of Chicago. Locational data of photographs were visualized by using Geographic Information Systems and helped in producing heat maps that showed the spatial distribution of posted photographs. Geo-intensity of photographs illustrated areas that are most popularly visited in the city. The study's results indicate that the city's skyscrapers along open spaces are major elements of image formation. Findings also elucidate that Social Media plays an important role in promoting places; and thereby, sustaining a greater interest and stream of visitors. Consequently, planners should tap into public's digital engagement in city places to improve tourism and economy.

Because Public organization also is developed in service fast, Public organization is trying to offer various service such as service level of enterprise. Each Public organization are trying to satisfy request of citizens as Customer. In this study, presented Kano-Servqual Method which is mixed by Kano's and Servqual model's advantage, each Method had used much in service quality measurement separately. Kano-Servqual Method is applied to the A information library as a public organization and is proved as practical useful method.

Big data information and pattern analysis have applications in many industrial sectors. To reduce energy consumption effectively, the eco-driving method that reduces the fuel consumption of vehicles has recently come under scrutiny. Using big data on commercial vehicles obtained from digital tachographs (DTGs), it is possible not only to aid traffic safety but also improve eco-driving. In this study, we estimate fuel consumption efficiency by processing and analyzing DTG big data for commercial vehicles using parallel processing with the MapReduce mechanism. Compared to the conventional measurement of fuel consumption using the On-Board Diagnostics II (OBD-II) device, in this paper, we use actual DTG data and OBD-II fuel consumption data to identify meaningful relationships to calculate fuel efficiency rates. Based on the driving pattern extracted from DTG data, estimating fuel consumption is possible by analyzing driving patterns obtained only from DTG big data.

A purpose of this research is to suggest a housing planning on a high-rise apartment by searching a residence lifestyle based on a trend. In this rapid changing age, this will be a based data for regulating the future social housing lifestyle by understanding a whole of social fields. In addition, residence who will be lived in a high-rise apartment will be likely to get a better life environment. By researching a trend with politics, social culture, economy, scientific technique from 1970 to 2008, it is came out the most important three trend is feminism, naturalism and digital. And these three main trend continuously affect people‘ lifestyle. The flow of trend, lifestyle and the complex apartment has been related each other. There are relation between housing flow and trend. This researching data can be used for the future high-rise apartment market introducing trend and lifestyle concept.

Recent lifeline with Internet and smart-phone is a new ICT-based revolution that has transformed the structure of economics and business activities in digital economy. This paper deals with some economic perspectives on the conceptual concerns on transaction costs and its applications to energy and environments, and glocalization strategies of e-business. First, we consider substantial differences between offline and online channel transactions and categorize three different aspects of transaction costs in the purchasing process in both channels. Second, we examine the impacts of e-business that affect sustainable environments and provide some considerations on energy savings, product-process design, and logistics. Finally, we present some opportunities and challenges posted by global e-business and outline the economics of networking in achieving enhanced performance and competitive advantage through glocalization strategies of e-business.

Participants in real-time online sessions, be it (business) meetings, virtual school lessons, or social live streams, all engage in cyber social interactions. Unlike parasocial interactions, cyber social interactions are characterized by reciprocity and temporal proximity. In contrast to social interactions, they lack spatial proximity and bodily contact. This is a fairly new concept in information science that rose from technological advances and unprecedented circumstances (e.g., the rise of digital economy and knowledge workers being able to work remotely or, more recently, global lockdowns and contact restrictions). As a result, the past ways of working and socializing were transformed by making them, in some cases predominantly, virtual. Regarding the example of social live streaming we exhibit the importance of cyber social interactions for information behavior research. This conceptual article is a plea for information science to engage more in human-human online relations and interactions.

Designers in Korea have stuck to development of furniture which has high reliance of foreign national resources. They made mistake that they didn't try to make inroads into the world market. They have kept production system of labor intensive method till 1990. They imitated foreign manufactures to win in domestic economy. It became the complete lack of exploitation experience and brought stagnation of design which couldn't defeat. Now Korea is making progressive impression in territory of an electron and information in a foreign market. A new progress of furniture design which was developed centering around a digital suggest a new appearance that will lead a future with modernization in a space of residence. This sis a new starting point which was most completed by anyone. If we will prepare without delay we can take part in a world market with competitive power.

South Korea has experienced various social problems during rapid economic development, and now attempts to address them through social economy and advanced technologies. This approach, however, requires comprehensive research on not only phenomenal issues but also their fundamental causes and regional/cultural contexts as Design Thinking Process does. This study aims to draw implications for applying Design Thinking Process into the entire process of solving social problems, from field research, idea refinement, and solution design. Limitations of Design Thinking-based social problem solving are also drawn through comparative analysis on various cases. In conclusion, the process of refining ideas and developing product/service can be utilized by social enterprises, ventures, NGOs, etc. as a guideline in addressing social problems.
