The role of information in knowledge society has changed. Library refers to information centre, which is actively involved information collection and promoting use of for the development of individual and society. Modern libraries are the centres of interaction for all interested in accessing information and in participating in the marathon of the present competitive age. Information and a conducive environment of its free flow is a vital tool in all forms of human endeavour. It is the link pin of national development. For a nation to develop it needs to have and provide relevant, updated and adequate information on food security, health, democracy, population, education, family planning, youth empowerment, gender quality, environment etc. The information intermediaries are the persons to modulate these complexities and find match between the information sources and users needs to satisfaction of Ranganathan's law: Books are for use; Every reader his/her book; Every book its reader; Save the time of the reader; Library is a growing organism. The relative importance of these norms in modern context has been evident from experience, study, observations, discussions, etc., and only by scientists and technologists, but also by managers, planners, and policy makers. They recognize the usefulness of information in the performance of their needs information needs. Libraries are therefore proper management, provision and dissemination of such information. It is clearly visible in the contemporary context, that the libraries in the knowledge society are much more than the book depositories This article looks at the theory/practice divide in library and information science and particularly Ranganathan's contributions, basic statements remain as valid in substance if not in expression as -to-day as when they were promulgated, concisely representing the ideal service and organizational philosophy of libraries today.

In real educational field, there are cases that concrete problematic situations are introduced after abstract concepts are taught on the contrary to process that abstract from concrete contexts. In other words, there are cases that abstract knowledge has to be concreted. Freudenthal expresses this situation to antidogmatical inversion and indicates negative opinion. However, it is open to doubt that every class situation can proceed to abstract that begins from concrete situations or concrete materials. This study has done a comparative analysis in difference of mathematical thinking between a process that builds abstract context after being abstracted from concrete materials and that concretes abstract concepts to concrete situations and attempts to examine educational implication. For this, this study analyzed the mathematical thinking in the abstract process of concrete materials by manipulating AiC analysis tools. Based on the AiC analysis tools, this study analyzed mathematical thinking in the concrete process of abstract concept by using the way this researcher came up with. This study results that these two processes have opposite learning flow each other and significant mathematical thinking can be induced from concrete process of abstract knowledge as well as abstraction of concrete materials.

This paper seeks to search for wisdoms that may be applied to modern leadership through Tasan Jeong Yakyong's ideology, ShilHak, from the Chosun Dynasty. The present period is referred as the period of transformation and innovation or the period of knowledge information The leadership appropriate for the current period is thus called revolutionary leadership. This leadership accomplishes its goals by influencing the constituent's values, ethics, behavioral norms, and visions based on the leader's moral values, knowledge, and information. Thus, the essence of this paper is in acquiring wisdoms of leadership by company revolutionary leadership with Tasan's life. Tasan pursued change and innovation in a time where Chosun was in a state of decay by following the flow of world powers towards the concept of studying truth based upon facts such as changing the system of thought, reforming legislation, and developing technology. Moreover, he gave courage and hope to the people by demonstrating such leadership in practice. In addition, despite false accusations and spending 18 years in exile, he showed revolutionary life as an active intellectual by leaving 542 volumes of writing through his 'value innovation' that he "pursue things only for the people and the state." Consequently, the paper first deals with what kind of leadership is required for a leader in the position of a general and examines the kind of leadership capacity demanded. Subsequently, Tasan 's revolutionary life and hints of leadership messages in MokMinSimSuh are examined. Thus, this paper is centered upon the leadership of generals regarding how MokMinShimSuh may be applicable to modern leadership.

An event means a flow which has a time attribute such as the a symptom of patients, an interval event has the time period between the start-time-point and the end-time-point. Although there are many studies for temporal data mining, they do not deal with discovering knowledge from interval event such as patient histories and purchase histories. In this paper, we suggest a method of temporal data mining that finds association rules of event causal relationships and predicts an occurrence of effect event based on discovered rules. Our method can predict the occurrence of an event by summarizing an interval event using the time attribute of an event and finding the causal relationship of event. As a result of simulation, this method can discover better knowledge than others by considering a lot of supports of an event and finding the significant rare relation on interval events which means an essential cause of an event, regardless of an occurrence support of an event in comparison with conventional data mining techniques.

The purpose of this study is to verify the correlation between leader's machiavellianism and turnover intention. To this end, we tried to investigate the overall mechanism of the research model through the mediating effect of hindsight bias. To verify the hypothesis, surveys were conducted twice with 335 employees working at companies with more than 300 employees in various occupations. As a result of the study, first, it was found that the machiavellianism of the leader had a positive significant effect on the employee turnover intention. Second, it was found that hindsight bias had a positive significant mediating effect between the leader's machiavellianism and employee turnover intention. It can be inferred that the higher the machiavellianism tendency of the leader, the higher the hindsight bias is experienced and the negative impact on the effectiveness of the organization, the higher the employee turnover intention. Therefore, this study in-depth verifies the mechanism between the leader's machiavellianism, hindsight bias, and employee turnover intentions, suggesting new implications from a perspective different from the existing research flow, and suggesting future research tasks and limitations on the role of leaders.

Investigations on the molten-pool sloshing behavior are of essential value for improving nuclear safety evaluation of Core Disruptive Accidents (CDA) that would be possibly encountered for Sodium-cooled Fast Reactors (SFR). This paper is aimed at synthesizing the knowledge from our recent studies on molten-pool sloshing behavior with solid particles conducted at the Sun Yat-sen University. To better visualize and clarify the mechanism and characteristics of sloshing induced by local Fuel-Coolant Interaction (FCI), experiments were performed with various parameters by injecting nitrogen gas into a 2-dimensional liquid pool with accumulated solid particles. It was confirmed that under different particle-bed conditions, three representative flow regimes (i.e. the bubble-impulsion dominant, transitional and bed-inertia dominant regimes) are identifiable. Aimed at predicting the regime transitions during sloshing process, a predictive empirical model along with a regime map was proposed on the basis of experiments using single-sized spherical solid particles, and then was extended for covering more complex particle conditions (e.g. non-spherical, mixed-sized and mixed-density spherical particle conditions). To obtain more comprehensive understandings and verify the applicability and reliability of the predictive model under more realistic conditions (e.g. large-scale 3-dimensional condition), further experimental and modeling studies are also being prepared under other more complicated actual conditions.

Metaverse is a combination of Meta and Universe, which refers to a world in which users or avatars engage in social, economic, and cultural activities. This study attempted to compare the four worldviews proposed by the Acceleration Studies Foundation (ASF) based on the five evaluation factors of SPICE, which are factors for promoting customer experience. 227 samples were used in the analysis, and as a result, seamlessness was the highest in augmented reality, interoperability in lifelogging, presence in the mirror world, and concurrence in virtual reality. This study is meaningful in that it presents a model design plan according to the classification of the metaverse platform and the worldview, and presents detailed strategic directions to existing metaverse platform operators or new entrants.

As the global energy and climate crisis has complicated interests of each country, the agenda that requires a global response has recently been revived. In particular, Korea is highly dependent on energy imports and continues to have high energy consumption, low efficiency of energy consumption, and high greenhouse gas emissions, so innovative and effective energy policies are urgently needed to achieve energy efficiency and carbon neutrality. In this study, among the changes in distributed district energy policy after the integrated energy method was introduced in Korea in the mid-1980's, the case of the "National Heat Map Project" policy implementation is analyzed with a modified multi-flow model. The 10 years of the Lee Myung-bak and Park Geun-hye administrations, the period of study, was a period in which the main paradigm of energy policy shifted to a "distributed energy platform" and policy transitions such as policy agenda setting, policy drift, and policy revision were made. A study on the process would be meaningful.

Science communication based on social reflection and political consensus among social members should be activated rather than focusing on science and trying to find solutions in a short period of time in order to respond to science and technology risk issues in modern society, which are the main characteristics of complexity, uncertainty, and unpredictability. The purpose of this study is to examine science communication suitable for a risk society and to present implications by exploring in detail how the concept and flow of science communication have changed due to changes in the social paradigm and what is needed to revitalize science communication. When scientific knowledge and understanding of science are combined with public participation, and science communication that can demonstrate practical expertise and efficiency can be realized when empirical knowledge to solve problems in a risk society is strengthened away from the authority and power of science alone.
