Concept mapping is a device for representing the conceptual structure of a subject discipline in a two dimensional form which is analogous to a road map. In the teaching and learning of earth science, each concept depends on its relationships to many others for meaning. Using concept mapping in teaching helps teachers and students to be more aware of the key concepts and relationships among them. The purpose of this study is to investigate the effect of the use of concept mapping on science achievement and the scientific attitude in ocean units of earth science. The results of this study are as follows; first, the science achievement of a group of concept mapping teaching is significantly higher than that of the group of traditional teaching. Also, when the achievement levels are compared among different cognitive ability groups, the effect is more significant in mid or lower level student groups than in high level groups. The use of concept mapping is more effective when the concepts have a distinct concept hierarchy. Second, the scores of the test of ‘attitude toward scientific inquiry’ and ‘application of scientific attitude’ of the group of concept mapping teaching are significantly higher than those of the group of traditional teaching, whereas the scores of the test of ‘interest in science learning’ of concept mapping teaching is not different from those of group of traditional teaching. Third, the survey on the use of concept mapping shows a positive response across the tested groups. The use of concept mapping is more beneficial in fostering the comprehension of the topic. A concept map of student's own construction facilitates the assessment of learning, thus promising the usefulness of concept mapping as a means of evaluation. In regard to retention aspect, concept mapping is considered to be more effective in confirming and remembering the topic, while less effective in the aspects of activity and interest. In conclusion, the use of concept maps makes learning an active meaningful process and improves student's academic achievement and scientific attitude. If the concept mapping is more effectively as an active teaching strategy, more meaningful learning will be attained.

The large amount of data that emerges from the initial connection environment of the Fourth Industrial Revolution is a major factor that distinguishes the Fourth Industrial Revolution from the existing production environment. This environment has two-sided features that allow it to produce data while using it. And the data produced so produces another value. Due to the massive scale of data, future information systems need to process more data in terms of quantities than existing information systems. In addition, in terms of quality, only a large amount of data, Ability is required. In a small-scale information system, it is possible for a person to accurately understand the system and obtain the necessary information, but in a variety of complex systems where it is difficult to understand the system accurately, it becomes increasingly difficult to acquire the desired information. In other words, more accurate processing of large amounts of data has become a basic condition for future information systems. This problem related to the efficient performance of the information system can be solved by building a semantic web which enables various information processing by expressing the collected data as an ontology that can be understood by not only people but also computers. For example, as in most other organizations, IT has been introduced in the military, and most of the work has been done through information systems. Currently, most of the work is done through information systems. As existing systems contain increasingly large amounts of data, efforts are needed to make the system easier to use through its data utilization. An ontology-based system has a large data semantic network through connection with other systems, and has a wide range of databases that can be utilized, and has the advantage of searching more precisely and quickly through relationships between predefined concepts. In this paper, we propose a defense ontology as a method for effective data management and decision support. In order to judge the applicability and effectiveness of the actual system, we reconstructed the existing air force munitions situation management system as an ontology based system. It is a system constructed to strengthen management and control of logistics situation of commanders and practitioners by providing real - time information on maintenance and distribution situation as it becomes difficult to use complicated logistics information system with large amount of data. Although it is a method to take pre-specified necessary information from the existing logistics system and display it as a web page, it is also difficult to confirm this system except for a few specified items in advance, and it is also time-consuming to extend the additional function if necessary And it is a system composed of category type without search function. Therefore, it has a disadvantage that it can be easily utilized only when the system is well known as in the existing system. The ontology-based logistics situation management system is designed to provide the intuitive visualization of the complex information of the existing logistics information system through the ontology. In order to construct the logistics situation management system through the ontology, And the useful functions such as performance - based logistics support contract management and component dictionary are further identified and included in the ontology. In order to confirm whether the constructed ontology can be used for decision support, it is necessary to implement a meaningful analysis function such as calculation of the utilization rate of the aircraft, inquiry about performance-based military contract. Especially, in contrast to building ontology database in ontology study in the past, in this study, time series data which change value according to time such as the state of aircraft by date are constructed by ontology, and through the constructed ontology, It is confirmed that it is possible to calculate the utilization rate based on various criteria as well as the computable utilization rate. In addition, the data related to performance-based logistics contracts introduced as a new maintenance method of aircraft and other munitions can be inquired into various contents, and it is easy to calculate performance indexes used in performance-based logistics contract through reasoning and functions. Of course, we propose a new performance index that complements the limitations of the currently applied performance indicators, and calculate it through the ontology, confirming the possibility of using the constructed ontology. Finally, it is possible to calculate the failure rate or reliability of each component, including MTBF data of the selected fault-tolerant item based on the actual part consumption performance. The reliability of the mission and the reliability of the system are calculated. In order to confirm the usability of the constructed ontology-based logistics situation management system, the proposed system through the Technology Acceptance Model (TAM), which is a representative model for measuring the acceptability of the technology, is more useful and convenient than the existing system.

The goal of this article is to examine the connection between creativity of unconscious and religion. Jung criticized how Freud's approach in studying the unconscious as a scientific inquiry focuses on the unconscious as reflecting only those which is repressed by the ego. Jung conceived of the unconscious as encompassing not only the repressed but also the variety of other psychic materials that have not reached the threshold of the consciousness in its range. Moreover, since human psyche is as individualistic as is a collective phenomenon, the collective psyche is thought to be pervasive at the bottom of the psychic functioning and the conscious and the personal unconscious comprising the upper level of the psychic functioning. Through clinical and personal experience, Jung had come to a realization that the unconscious has the self-regulatory function. The unconscious can make "demands" and also can retract its demands. Jung saw this as the autonomous function of the unconscious. And this autonomous unconscious creates, through dreams and fantasies, images that include an abundance of ideas and feelings. These creative images the unconscious produces assist and lead the "individuation process" which leads to the discovery of the Self. Because this unconscious process compensates the conscious ego, it has the necessary ingredients for self-regulation and can function in a creative and autonomous fashion. Jung saw religion as a special attitude of human psyche, which can be explained by careful and diligent observation about a dynamic being or action, which Rudolph Otto called the Numinosum. This kind of being or action does not get elicited by artificial or willful action. On the contrary, it takes a hold and dominates the human subject. Jung distinguished between religion and religious sector or denomination. He explained religious sector as reflecting the contents of sanctified and indoctrinated religious experiences. It is fixated in the complex organization of ritualized thoughts. And this ritualization gives rise to a system that is fixated. There is a clear goal in the religious sector to replace intellectual experiences with firmly established dogma and rituals. Religion as Jung experienced is the attitude of contemplation about Numinosum, which is formed by the images of the collective unconscious that is propelled by the creativity and autonomy of the unconscious. Religious sector is a religious community that is formed by these images that are ritualized. Jung saw religion as the relationship with the best or the uttermost value. And this relationship has a duality of being involuntary and reflecting free will. Therefore people can be influenced by one value, overcome with the unconscious being charged with psychic energy, or could accept it on a conscious level. Jung saw God as the dominating psychic element among humans or that psychic reality itself. Although Jung grew up in the atmosphere of the traditional Swiss reformed church, it does not seem that he considered himself to be a devoted Christian. To Jung, Christianity is a habitual, ritualized institution, which lacked vitality because it did not have the intellectual honesty or spiritual energy. However, Jung's encounter with the dramatic religious experience at age 12 through hallucination led him to perceive the existence of living god in his unconscious. This is why the theological questions and religious problems in everyday life became Jung's life-long interest. To this author, the reason why Jung delved into problems with religion has to do with his personal interest and love for the revival of the Christian church which had lost its spiritual vitality and depth and had become heavily ritualized.
