  • In the digital society where ICT technology is highly developed, digital literacy is an essential competence for working and living. Developed countries around the world have been working hard to solve the digital divide and improve digital literacy. In this paper, we investigated and analyzed the case of US public libraries for improvement of digital literacy of adults including the older people. To do this, we analyzed the educational program type of digital literacy, education method, and the contents of the program, focusing on the best practices libraries of the program. Many of the educational programs still related to basic computer and Internet technologies, and training programs on Micro Office, e-mail, social media, and smartphone and tablet computing were also high. The most frequent and daily training method was informal point of use, and the content and level of education appeared to be very diverse. For digital literacy training, the librarians of the public library considered librarians' digital competence and retraining to be the most important, and the library facility and the latest equipment to be suitable for the operation of the digital literacy education program.

  • This study considers the availability, accessibility, and efficacy of social services for migrant workers. First, it examines migrant workers needs and how they choose to fulfill these. Second, this study grasps about how they can connect the social services and what constructive peculiarities social networks they have by using SNA(Social Network Analysis) it is revealed that migrant workers rely more on informal support groups such as family, friends, co-workers, etc. rather than formal support networks, e.g. those provided by the state. This tendency is demonstrated especially, Libraries as formal supporting organization have no connection related with other organizations. It shows that they have role limited as a supporter of giving information and knowledge in a public.

  • Smart grid that supports efficient energy production and management is used in various fields and industries. However, because of the environment in which services are provided through open networks, it is essential to resolve trust issues regarding security vulnerabilities and privacy preservation. In particular, the identification information of smart meter is managed by a centralized server, which makes it vulnerable to security attacks such as device stolen, data forgery, alteration, and deletion. To solve these problems, this paper proposes a blockchain based authentication protocol for a smart meter. The proposed scheme issues an unique decentralized identifiers (DIDs) for individual smart meter through blockchain and utilizes a random values based on physical unclonable function (PUF) to strengthen the integrity and reliability of data. In addition, we analyze the security of the proposed scheme using informal security analysis and AVISPA simulation, and show the efficiency of the proposed scheme by comparing with related work.

  • In Korea the concept of social support was first used as a research concept in nursing and has not had much application in the clinical field. Another problem is that research on social support has used a direct translation of the words “social support” into Korean as “sawhejuk jiji”. Three questions were posed to direct the re-search. 1) Is there a concept of social support in Korean society? 2) if so, what words or expressions are used to de-scribe it? 3) further, if so, how is social support structured and how does it function? In order to answer the research questions a three-step research methodology was used : The first step consisted of a literature review on re-search related to social support and on information on the background of, and the way of thinking re-lated to interpersonal relations among Korean people. The second step, which was done to identify whether there is a concept of social support in korean society, involved interviewing a sample of the population. The third step involved a panel discussion that included the members of the research team and three consultants, a sociologist, a philosopher and a scholor in korean literature. A review of the literature on interpersonal relationships in traditional korean society identified a four cirole structure that explains interpersonal relationships. The first circle with “me” at the center is the family but here “me” disappears into the “we” that is essential for a cooperative agricultural society. In the second circle are those close to “me” but outside the family. The third circle includes those with whom “I ” have infrequent but regular contact and with whom correct conduct is important. The last circle is all the people with whom “I” have nothing in common. They are excluded in interpersonal relationships. The literature on interpersonal relationships showed that within the traditional Korean society people lived in villages where most people were very familiar with each other. “Yun”, the social network established the connection and “Jung”, the feeling of affection increased with time as the connection was strengthened. In the traditional village psychological support was provided through “Mallaniki”, “Pumashi” and “Kae” with the latter two also providing material support. In modern Korea there are more informal and formal social networks, like social services and community activities on the formal level and cultural and leisure groups along with “kae’s on the informal level. But even with this modern variety of groups, most social support comes from informal networks that resemble the traditiorlal “Pumashi”, “Kai” md “Mallaniki”. The six member research team interviewed 65 people in order to identify whether there is a concept of social support and then analysed their responses. There were 20 different words describing the reception of the social support and these could be grouped into seven major categories : virtuous, fortunate, helped, supported, blessed, attached(receiving affection) and receiving (grace) benevolence. there were 27 words describing the act of social support which could be categorized into seven major categories : love, looking after, affection(attachment), kindness(goodness), faith, psychological help and material help. for the meaning of social support translated as “sawhe juk jiji” there were a total of 14 different answers which could be categorized into 3 major categories : help, agreement, and faith. In third step, the results of the literature review and the answers to the questions were discussed in a pannel. The results of the discussion led to the following definition of social support in Korea which is shaped like a the four sided pyramid on a base. Social support is the apex of the pyramid and four sides are made up of : “do-oom” (both emotional and material help), “jung” (connectedness, or relationship bound by affection, regard or shared common experience ), “midum” (faith or belief in), “eunhae” (kindness or benevolence). The research team identified “Yun”( the basic network of relationships) as the base of the pyramid and as such the foundation for the components of social support in Korean culture. On “Yun” rest the other four components of social support : “Jung”, “Midum”, “Do-oom”, and “Eunhae”, For social support to take place there must be “Yun”. This is an important factor in social support. In private social network “Jung” is an essential factor in social support. But not in the public social network. “Yun” is a condition for “Jung” and “Jung” is the manifestation of support.

  • The prior studies on the practical lawyer's information seeking behaviors, including Leckie et al. (1996) model showed that role of the work and nature of the work in attorney's practices had an significant influence on the attorney's information seeking behaviors. This study now asks if these prior analyses can be applicable to attorneys' practices nowadays. This study performed surveys and interviews with 21 practical attorneys in korea who were grouped by their experience period and the size of law firms. This study concludes that role of the work in Leckie et al. model still affects the attorneys' information seeking behaviors today and moreover, the attorney's experience and the size of law firms as variables also have made an impact on attorney's behaviors so far. By the way, this study further finds that the attorneys prefer the digital information in online database and formal information like statutes or case laws. These results are definitely different from them of the prior studies. In addition, this study suggests that the behavior such as meaningful using of the informal information in difficulties with improper information can be kinds of the attorney's information seeking behaviors.

  • This research attempts to verify the hypothesis that the workers in the small-and medium-sized industries use more informal information channels than formal ones do to get the information necessary to industrial activities. Information sources are divided by the internal and the external ones and these are sub-divided by their acquiring channels, publishers and holding institutions. It is intended to investigate the information sources according to the use frequency, age, origin and format of documents used. The degree of benefit to the workers in their practical work through the use of information sources and the use frequency of information sources by the department and years of experience are also investigated. The data to test the hypothesis was collected through the questionnaires distributed to the workers in 300 sampled firms from June 5 to June 20, The following facts have been verified as the result : 1. Workers in industries acquire information mainly through the contacts with the colleagues or superiors in their departments, and the junior workers depend more on the colleague and superiors than senior workers are. 2. Among the documents published internally, the ones from the research and development departments are mostly used. The documents issued by the worker's own departments are also frequently used and the senior workers, the more frequently use the internal publications than the junior workers do. 3. Among the internal documents stored in various places in the industries, the documents kept in the worker's own departments are used most frequently. The senior workers the more use privately owned documents than the junior workers do. 4. As far as the external channels are concerned, information is obtained mainly through suppliers of equipment and raw materials and the use frequency of information channels varies according to department. The senior workers the more receive information through supporting institution, seminar and exhibition than the junior workers do. 5. Among the external publication, the ones published by the industrial supporting institutions are heavily used and the workers in research and developments frequently use the external publications. 6. The documents held in governmental industrial institutions and industrial supporting institutions are heavily used compared with the ones stored in other external institutions. The holding places of frequently used documents vary according to the working departments. 7. The degree of benefit to practical work performance resulted from the internal information use is less than by the use of external information. 8. The documents published more than five years ago are more used than the ones of less than five years, Korean and Japanese documents are used frequently and catalogues, patents and standards are used to a great extent. The documents are used differently in accordance with work departments.

  • Parents' interest and care are very important for their children in the process of growing up, but parenting is also very unfamiliar and difficult for themselves. Parents constantly need information related to parenting, and in order to solve this problem, they try to obtain information through informal meetings or social relationships among parents at an individual level, which often brings up conflicts and stresses. Accordingly, the purpose of this study is to explore the characteristics of social networks among parents and to understand the influence of the network characteristics on information-sharing intention and information-sharing satisfaction. To this end, a survey questionnaire was developed based on previous studies and was administered among parents whose children are in a daycare center. Then, the data was analyzed using social network analysis (SNA) method. Findings indicate that the correlation among the social networks, the information -sharing intention, and the information-sharing satisfaction was significant, but the influence of the social networks on the information-sharing intention, and the information-sharing satisfaction was not established. It was also found that the intention to receive help was higher than the desire to help others. Policy suggestions to meet parents' information needs and the need to reconsider the role of local public libraries were presented.

  • This paper attempts to show the status and network characteristic of regional innovation support agencies(company support agencies and R&D institutes, RISA) which play an important role in the regional system of innovation in Daegu City, using questionnaire data. Most of these agencies were established in 1990s and tend to locate in Buk-Gu and Dalsu-Gu, being major local universities which retain a large number of R&D and industry support agencies. The business areas of the agencies are largely associated with business training and applied research. Their major role is to provide the information that local firms need to acquire. It shows that they have relationships with 1 to 5 agencies, primarily in the form of informal network, for the purpose of sharing information and knowledge about science/technology and market trend. There are not many spin-offs from RISA. But most of spin-offs from RISA are located in Daegu City and maintain cooperative relationships with their parent organization primarily in the form of formal network. The main purpose of cooperative relationships with RISA is to interchange knowledges about technology.
