The prototype of a library is analysed upon the facts that are generalized and recognized as commonsense. On the extension of the prototype, a digital library is considered. Ultimately the libraries' prototype should be steady at any time. A library which is being a digital library to which the best technology at that time applies, should function as the creator of the value by publishing, circulating, and re-production of the information resources.

I have discussed some problems of distortion in reading education. I think we must give careful consideration to the true meaning of reading to overcome the matter. From the position of the readers I have looked into the true meaning or reading and cases of reading programs. I presented the directions for a new reading program.

Modern society is rapidly developing into the Internet of Things and Big Data, and there are industries that develop even in the Corona era. However, the church is not developing and responding enough to the Corona era, and it is shaking the existence of the church itself. The essence of the church consists of worship, evangelism, education, service, and companionship. In the era of Corona, where non-face-to-face safety is important, the essence does not change, but efforts to embody the essence of the church in a socially responsible manner are needed. This paper discusses the social responsibility of the church in this respect, focusing on the five essential elements of the church. To this end, we examine the essential elements of the church and study the implementation methods suitable for the Corona era.

Areas of concentrations that can be exploited at all times, such as gas reservoirs in crude oil tanks, are called zero zones. In order to use various equipment in Zone 0, an intrinsically safe certification must be obtained that can guarantee that sparks will not occur in nature. Most devices that acquire intrinsic safety certification are mostly simple single-component devices or devices. In this study, it was a very difficult process because we intend to acquire the intrinsic safety certification of an electronic circuit including an ultrasonic generator and a microcontroller in which hundreds of components are mounted on a PCB substrate. Through this study, we have been able to understand how to design a circuit for intricate intrinsic safety certification. and Using the results of this study, it will be easier to design intrinsically safe circuits when trying to develop a circuit that can obtain intrinsic safety certification.

Psychological essentialism states that people believe some categories to have hidden and defining essential features which cause other features of the category (Gelman, 2003; Hirschfeld, 1996; Medin & Ortony, 1989). Essentialist belief on categories questions the Roschian argument (Rosch, 1973, 1978) that categories merely consist of clusters of correlated features. Unlike family resemblance categories, essentialized categories are likely to have clear between-category boundaries and high within-category coherence (Gelman, 2003; Prentice & Miller, 2007). Two experiments were conducted to test the effects of essentialist belief on category representation (i.e., between-category boundary, within-category coherence). Participants learned family resemblance and essentialized categories in their assigned conditions and then performed categorization task (Expt. 1) and frequency estimation task of category exemplars (Expt. 2). The results showed, in essentialized categories, both boundary intensification and greater category coherence. Theses results are likely to have arisen due to increased cue and category validity in essentialized categories and suggest that essentialist belief influences macroscopic representation of category structure.

The purpose of this study is to critically examine science content and science education from the 'essential-holistic' perspective, in particular, among the core disciplines constituting the teacher education curriculum. In this study, we first, analyzed the definition of the 'essential-holistic' perspective, the philosophical background, and the relationship with the practices in-depth, and then, from the 'essential-holistic' perspective, conducted an inquiry into the essence of science content and science education. The results of this study are as follows: first, according to the 'essential-holistic' perspective, science content is a study that explores the science practices and systematizes the results of that inquiry. Major activities of science content include the establishment and implementation of 'science for teachers' and participation in the development of science curriculum (textbook). Second, science education according to the 'essential-holistic' perspective is a study about in-depth exploration of essential problems in science education phenomena rooted in the science practices and the practice of good teaching. More specifically, science education is a field that carries out work related to inviting, participating, and guiding students to grow into science practices (i.e. initiating into practices). The main activities of science education related to this include activities ranging from the development of the science curriculum (textbook) to teaching and evaluation (recording). In this study, we discussed important tasks to be carried out in the future based on the results of the study.

The current research investigates an optimal design for the service system, which refers to the entire process of implementing, providing, and utilizing wisdom assets. We analyzed the intrinsic commonality of wisdom assets and services, and carried out research based on optimality in fidelity to service essence. The essential characteristics of service are horizontality, interactivity, harmonization, and relationship. It is suggested that the operating process can be implemented in the best condition when the wisdom asset service system is designed based on the four essential characteristics of services. It has been demonstrated that the entire process of production, delivery, marketing and quality control of wisdom contents can be designed on the basis of the essence of wisdom and service. After designing a basic service model, detailed service models are presented. The purpose of this study was to solve the problems of the material civilization society which is suffering mentally and to design the social service model which is high in productivity but mentally healthy. By supplementing and deepening the results of this study, it will be possible to develop and implement desirable social service model in which all societies live a happy life.

This study conceptualized the essence and propensity of modern management in service age, based on philosophy, and developed items to evaluate the conceptualized content. It was carried out as a new study to deepen the study of management philosophy and management theory by the new management framework. In order to establish the philosophical foundation of the modern management, the essence of the modern management was conceptualized based on the fundamental ideas of the East and West, and then an evaluation item was developed to put the essence and propensity of the modern management into practical use through analytical and empirical methods. After analyzing the representative ideas of mankind, it was derived that the Book of Change has the qualification as a philosophical model that can derive the essence of modern management. The Book of Change explains the reasoning of the world in the structure of two opposing parties, such as Taiji or Yin and Yang, and the process of acknowledging the contradictions within each opposing party and overcoming the contradictions through change is the central idea. Because you can see. After conducting a conceptual study, through empirical research, the essence and propensity of a modern manager should be conceptualized. The concept of essence and empirical study of the modern management using the leading role was conducted in two stages. First, a qualitative study using repetitive comparative analysis (CCM), focus group interview (FGI), and text mining was conducted to derive the essential and propensity conceptualization items that modern managers should possess. In addition, a quantitative study using factor analysis to develop sample items and develop measurement items through literature review and FGI was conducted to derive the essential concept of the modern management. Finally, the essence of modern management was derived: learning, preparation, challenge, inclusion, trust, morality, and sacrifice. In the future, it is necessary to conduct empirical research on the effectiveness of the essence of modern management for global and Korean representative companies.

최근 들어 안전관리의 패러다임은 사후분석에서 사전예방으로 바뀌고 있다. 이러한 추세에 맞추어 본질적인 안전관리에 대한 관심이 늘어나고 있다. 공정에 본질적인 안전을 추구하는 방법은 크게 5가지로 나누어 질 수 있으며, 공정의 배치를 통해서 사고를 영향을 최소화하는 방법은 공정의 설계단계에서 적용할 수 있는 좋은 방법이다. 본 연구에서는 공정의 설비가 가지는 위험성을 기반으로 안전거리에 대한 지침을 제시하고 있다. 사고결과와 사고발생빈도를 기반으로 개인적 위험성(Individual Risk: IR)을 계산하였으며, 계산된 값을 기반으로 최적의 안전거리 계산을 수행할 수 있었다. 계산된 IR과 문헌에서 제시된 안전거리를 바탕으로 작업자가 거주하는 건물과 공정경계 까지의 적절한 거리와 설비간의 최적의 거리를 계산하게 된다. Mixed Integer Linear Programming(MILP)를 이용하여 각각설비의 안전거리가 확보된 시설물 배치와 최소 부지 면적 등을 알 수가 있다. 이 연구를 통해 최적화된 부지면적과 파이프라인의 시설물 배치는 물론 공정건설이나 초기 디자인 단계 및 안전성확보측면에서 본질적인 안전을 구현하는데 유용하게 적용될 수 있다.
