Social media is a general term for online services by which users share opinions, perspectives, and experiences. It supports interactions between users in sharing contents on it and weak ties among them play an important role in the process. This exploratory study attempts to identify crucial factors of establishing weak ties between social media users in the perspective of social network theory and uncertainty reduction theory. We collected data through diary study and in-depth interview and analyzed it following grounded theory approach. As a result, social media users more actively interacted each other or shared contents based on weak ties, compared to strong ties. In addition, similarity, self-disclosure, and relevance appeared to facilitate establishment of weak ties, by reducing psychological distance between social media users and perceived uncertainty of them.

Informatization in Korea has undergone significant changes. So far, most studies on informatization policies have been carried out just on the basis of their structural or functional backgrounds. However, actually, informatization policies have changed dynamically as a lot number of people and organizations have participated in their formulation and implementation. So, this study approaches them with an actor-network view that is distinct from but contains a chronological perspective, which other studies have overlooked so far. This approach allows us to have a clear picture of the changes in and to look into the characteristic of informatization policies from the Chun Doo Hwan government to the Lee Myung-bak government. Consequently, on the basis of the actor-network view, it is found that information and communication technologies, knowledge, and professionalism have dominated the characteristics and streams of informatization policies and brought about changes.

According to the $7^{th}$ reform of high school education curriculum, contents on probability and statistics in mathematics of high school curriculum have been expanded compared to the previous curriculum. Thus if the curriculum contains the contents to achieve the goals for probability and statistics, more efficient education on statistics is expected to meet the needs of information age. In this thesis, we studied through network analysis if contents on probability and statistics in mathematics of high school curriculum are composed to achieve the goals. We reviewed contents on probability and statistics in mathematics of the $7^{th}$ reform of high school curriculum whether they are conformed the purpose and direction of the reform or not. As a result, the concept of probability distribution and statistical estimation with a random variable was described clearly. But, census and sample survey were not connected with other items. In a part, there were expressional mistakes.

The purpose of the study compares the difference between the carriers' reported large consumption emotion of customers in regards to the appearance of the crew. The research method was conducted for 15 days from March 11 to 25, 2018, and the number of valid samples was 289 in total. The results of the study showed that customers differ in the influence of perceived consumption sentiment between full service carrier and low cost carrier on uniform of flight attendant. Consumer sentiments perceived by low cost carriers are comfortable, familiar, and lively, and these results have proven that they are distinguished from low cost carriers by being clean, sophisticated, and large. The results of this study are significant when the airline has changed the crew uniform at the right time and considered it to be a marketing tool that is important to the image change of the company.

The fundamental concerns of this paper are to analyze the effects of some characteristics on the employment of new college graduated students in viewpoint of data visualization. We use individual and department characteristic data of K-university graduated students in 2010. We apply multiple correspondence analysis, decision tree analysis, association rules and social network analysis for data visualization. The results of the analysis are summarized as follows. First, an analysis of the determinants of employment shows that GPA, department category, age and number of majors, recruiting time affect the employment rate. Second, higher GPA and natural category of department positively affect the employment rate. Finally, low age, single major and early recruiting time also positively affect the employment rate.

The special means of transportation introduced to improve the mobility of the transportation vulnerable met the number of legal standards in 2016, but lack of development in terms of quality, such as the existence of long waiting times. In order to streamline the operation of special means of transportation, long-term standby traffic, which is the top 25% of the wait time, was extracted from the Daegu Metropolitan Government's special transportation history data, and spatial autocorrelation analysis and social network analysis were conducted. As a result of the analysis, the correlation between the average waiting time of special transportation users and the space was high. As a result of the analysis of internal degree centrality, the peak time zone is mainly visited by general hospitals, while the off-peak time zone shows high long-term waiting demand for visits by lawmakers. The analysis of external degree centrality showed that residential-based traffic demand was high in both peak and off-peak hours. The results of this study are considered to contribute to the improvement of the quality of the operation of special transportation means, and the academic implications and limitations of the study are also presented.

The Purpose of this study is the applicaion of social network analysis for expanding the use of spatial data in local government. Spatial data generated from UIS projects play very important roles as a means of supporting decision making and solving complicated urban problems, but the utilization of the spatial data has not reach the expected level, considering to the huge amount of investment. Accordingly, there should be efforts in efficient management of spatial data, establishment of a sharing system, and expanded utilization of spatial data. Social network analysis applied to this research is a theory that explains the behaviors and patterns of units forming the system and measures distances between nodes, strength, etc. based on relations among nodes forming the network and the structural characteristics of the network. According to the results of surveying civil servants who were using spatial data on Busan Metropolitan City, obstacles to the sharing of spatial data were mostly non technical factors related to data users' attitude and their relations with circumstances. In order to expand the use of spatial data, this study performed social network analysis that applied the theory of planned behavior and examined the flow of spatial data, and by doing so, we analyzed related personnel's perception, identified obstacles to data sharing, and suggested a framework for promoting the expanded utilization of spatial data.

Home Networking is the last connection point for global information and telecommunication infrastructure establishment. Information infrastructure has been constructed to matured extent so far, and then the enhancement of data transferring performance and high speed capacity in houses tame to the problem to solve as the last communicating area. In addition, to hold such communicating rapacity in houses, the customer premises technology is important as the framework. In this paper, introducing various home networking technologies, prospect of premise technology is reviewed.
