COVID-19 provided visitors with new online concerts that gradually increased in many ways. The disadvantage of current online concerts is that cannot make full use of the interaction with others. We hope to provide online concert audiences with the same experience as offline. This study was conducted under the condition that the audience watched online concerts and movies individually or group. Experimental results confirm that watching online concerts collectively will increase the sense of immersion. It can be used as a design guide for the virtual public viewing environment in the future.

The Qi(氣) concept in the Orient is the important concept which forms the world-view and thinking structure of the Oriental. The idea of Qi unfolds two ways. The first is the cosmogony that is the theory explaining the creation and change of universe through the change of Qi. The second is the preservation theory that think human body is full of Qi and we can be the immortal by raising Qi inside human body. The canon of Daesoonjinrihoe(大巡眞理會), Jeon-gyung(典經) also says about Qi many times especially in the doctrines about the object of belief and Cheonjigongsalon(天地公事論). This paper is willing to systematize the discussion of Qi in Daesoon(大巡) thought through researching Sangjeguan (上帝觀) and Cheonjigongsalon. The object of religious faith in Daesoonjinrihoe is Gucheon(九天)-yeungwon(應元)-noisung(雷聲)-bohwa(普化)-cheonjon(天尊)-gangsung(姜聖)-sangje(上帝) and Won(元) concept in the explanation of this divinity is deeply related to Wonqi(元氣) thought of the Oriental traditional Qi idea. And the theory of Qi(Qilon, 氣論) in Sangjeguan is related to electricity and the idea that the supreme God governs all things by electricity is the very original interpretation only found in Daesoon thought. The Qilon in Cheonjigongsalon is based on the Qilon of traditional thought that sees Qi is the element of all things and all thing are formed by the change of Qi. And the unique feature of the Qilon is saying that the supreme God, Cheungsan(甑山) operates Qi of universe and arouses the change of Qi. That is to say, God Cheungsan saved the world and all living beings by eliminating and giving and changing and moving and gathering and combining Qi. The characteristics of Qilon in Cheonjigongsalon is that the transcendental existence having human body has the control of the change of Qi in the universe. In conclusion, Qilon of Dasesoon thought tells that Gucheon-Sangje Chengsan governs all things by electricity and he fixed the old world and opened the new world like paradise by conducting the change of Qi.

The study of human erroneous actions has traditionally taken place along two different lines of approach. One has been concerned with finding and explaining the causes of erroneous actions, such as studies in the psychology of "error". The other has been concerned with the qualitative and quantitative prediction of possible erroneous actions, exemplified by the field of human reliability analysis (HRA). Another distinction is also that the former approach has been dominated by an academic point of view, hence emphasising theories, models, and experiments, while the latter has been of a more pragmatic nature, hence putting greater emphasis on data and methods. We have been developing a method to make predictions about error modes. The input to the method is a detailed task description of a set of scenarios for an experiment. This description is then analysed to characterise thd nature of the individual task steps, as well as the conditions under which they must be carried out. The task steps are expressed in terms of a predefined set of cognitive activity types. Following that each task step is examined in terms of a systematic classification of possible error modes and the likely error modes are identified. This effectively constitutes a qualitative analysis of the possibilities for erroneous action in a given task. In order to evaluate the accuracy of the predictions, the data from a large scale experiment were analysed. The experiment used the full-scale nuclear power plant simulator in the Halden Man-Machine Systems Laboratory (HAMMLAB) and used six crews of systematic performance observations by experts using a pre-defined task description, as well as audio and video recordings. The purpose of the analysis was to determine how well the predictions matiched the actually observed performance failures. The results indicated a very acceptable rate of accuracy. The emphasis in this experiment has been to develop a practical method for qualitative performance prediction, i.e., a method that did not require too many resources or specialised human factors knowledge. If such methods are to become practical tools, it is important that they are valid, reliable, and robust.

Vertigo refers to a state in which awareness related to the location, posture, movement, etc. of a helicopter is insufficient in space. It is easy to fall into flight illusion when flying in dense fog or night flight, and even if it has a wide field of view, it can be caused by visual causes such as cloud shapes, wind conditions, conditions of ground objects, and sensory causes such as changes in air posture or gravitational acceleration. The design and program of the motion system are studied that applied a six-axis motion system to a conventional commercial flight simulator program for pilot training, depending on the specificity of helicopter flight training that requires perception and sensitivity. Using the motion-based helicopter simulator produced in this study to train pilots, it is expected to have a positive effect in prevent of vertigo, where high performance could not be confirmed in the previously used visual-based simulation training device.

KASS (korea augmentation satellite system) is an SBAS (satellite based augmentation system) that must ensure the performance of aviation service in accordance with the International Civil Aviation Organization's SARPs (standards and recommended practices) Annex 10 - Aeronautical Telecommunications. In order to guarantee the target service performance, the operating system must be operated, maintained and managed stably, and a maintenance system must be established for this purpose. From the maintenance point of view, the KASS subsystems were developed to consist of replacement units, and the maintenance organization and procedures to manage those subsystems and units were defined. In addition, the maintenance task for each the replacement unit was developed to ensure the availability performance required for the successful KASS operation, and the developed tasks were verified to sufficiently cover the activities to maintain the previously defined replacement units. The maintenance tasks developed through this study will be continuously verified in the actual operation preparation process prior to the full-scale provision of aviation services in the end of 2023, and will be updated accordingly.

ShadowCam is a high-sensitivity, high-resolution imager provided by NASA for the Danuri (KPLO) lunar mission. ShadowCam calibration shows that it is well suited for its purpose, to image permanently shadowed regions (PSRs) that occur near the lunar poles. It is 205 times as sensitive as the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC). The signal to noise ratio (SNR) is greater than 100 over a large part of the dynamic range, and the top of the dynamic range is high enough to accommodate most brighter PSR pixels. The optical performance is good enough to take full advantage of the 1.7 meter/pixel image scale, and calibrated images have uniform response. We describe some instrument artifacts that are amenable to future corrections, making it possible to improve performance further. Stray light control is very challenging for this mission. In many cases, ShadowCam can image shadowed areas with directly illuminated terrain in or near the field of view (FOV). We include thorough qualitative descriptions of circumstances under which lunar brightness levels far higher than the top of the dynamic range cause detector or stray light artifacts and the size and extent of the artifact signal under those circumstances.

This study examines the perception and trust of Korean society and people among students and adults using the indigenous psychological analysis. A matched sample of 1,107 participants, consisting of 369 students, their mothers and their fathers completed a questionnaire developed by the present researchers. The results indicate that parents more likely than adolescents to hold negative views of Korean society. Adults are more likely than adolescents to view Korean society as showing high ingroup favoritism, to be insecure, to be conservative, to be corrupt, and to have social inequities. Both groups agree that Korean society is not rational nor democratic, but believe that it has the potential for progress. Second, parents are more likely to hold negative views about Korean people. Adults are more likely than adolescents of viewing Korean people as overly conscious about social face, emotional, selfish, exclusionary, and conceited. Both adolescents and their parents agree that Koreans are cooperative, full of jung (deep affection and attachment), and sincere. Third, adults are less likely to trust Korean institutions than adolescents. Adults are less likely than adolescents to trust National Assembly, political parties, and unions. Adolescents are more likely than their parents to trust family members, school friends, teachers, and government employees. These results indicate that adolescents have higher trust of Korean society and people than their parents. Fifth, the overall results indicate that both group perceive Korean society as showing high ingroup favoritism and corruption. In terms of Korean people, respondents had a more balanced view of perceiving them as highly sensitive to social face and being emotional, while also perceiving them as cooperative and full of jung. The trust of Korean institutions were generally low, especially the National Assembly and political parties. However, the trust of family was very high, followed by trust of school friends and teachers. The trust of government employees was low and this was especially the case for politicians.

The view of life and death in Daesoonjinrihoe includes all the gods of Heaven and Earth, and the human heart is taken as the foundational key. Practitioners can realize their value according to how much they have cultivated themselves. This is regarded as the mythical use of a singularly focused mind (full dedication of one's heart). In other words, it focuses on the potentiality of humans who are able to enter a transcendental area of divinity through their self-cultivation. This view of life and death in Daesoonjinrihoe was established by the religious mission known as "Samgye Gongsa (the Reordering of Three Realms of Heaven, Earth, and Humanity)." Samgye Gongsa indicated a new opening of the Three Realms of Heaven, Earth, and Humanity. This new opening is a return to the original principle of Heavenly operation and also a new order for the universe. Heaven and Earth have their own underlying principle by which they operate. This act was directly initiated and manifested from Dao. Daesoonjinrihoe diagnoses that the underlying principle by which Heaven operates was damaged by human misconduct, and as a result, the human observance of that principle fell out of common usage. Therefore, Daesoonjinrihoe gives priority to the reestablishment of Dao as it existed originally and tries to bring about reconciliation between Heaven and Earth and Humanity. In short, it resolves the grievances accrued since time immemorial by correcting the order of Sindo (Divine Law). Furthermore, it shows that the Dao of Sangsaeng (mutual beneficence) was created by reordering the arrangement of Heaven and Earth so that human beings and divine beings could reach a state of perfection through self-realization. Humans not only communicate with Heaven and Earth, but also communicate with divine beings. Divine beings are transcendent living beings capable of communicating with humans through their heart-minds. In Daesoon thought, human beings are not swayed by the power of divine beings, but instead are able to control divine beings through the transcendent power of their heart-minds. Given this view, the aim of Daesoonjinrihoe lies in participating in the harmony of Heaven and Earth through the cultivation of the human heart. Also, it sees that the human heart-mind can be united with the universal Dao, and thus it is able to be united with the deities of Heaven and Earth. In order to actualize this, one does not rely on exterior rituals or magic but has to focus instead on cultivating the moral ethics of the heart-mind to reach perfection. In other words, one can reach a transcendent level in one's heart-mind through the cultivation of a singularly focused mind and be free from the contradiction of life and death and other such torments. Life and death is an inevitable process for humans. So they do not have to be happy for life and sad for death. They can rather be free from the fear of death by fulfilling the energetic zenith of the human heart-mind via training themselves to transcend their physical bodies. No aging and no death is not a pursuit of radical longevity or immortality for the physical body, but rather a pursuit of the essence of life and the realization of eternity on a spiritual level. Daesoonjinrihoe pursues the state of being unified with Dao by developing "Jeong·Gi·Sin (精·氣·神 the internal energies of essence, pneuma, and spirit)" and trying to reach the transcendent state of non-aging and radical longevity by spurring the practice of self-realization and the discovery one's own innate nature. Through the practice of human ethics, they can access the creative functions of Heaven and Earth and become one with Heavenly Dao thereby achieving harmony between temporal existence and eternity. In this way, humans transcend the life and death of their physical bodies. When "Doins (trainees of Dao)" reach the true state of unification with Dao through singularly focused cultivation, they not only realize self perfection as human beings, but also enable themselves the means to do away with all disasters and forms of suffering. They thereby attain ultimate happiness in their lives.

With the ever-increasing importance of high-speed information in society as we move towards the 21 st century, telecommunication laboratories of advanced nations are pressing forward with research and development aimed at implementing its W & P(Visual Intelligent and Personal) services and construction of a new network to support them. In legals to the former, based on a long-term view of technological and market trends, those laboratories are researching and developing services that will make possible an effective progression from the development of services that answer to potential needs towards the full-scale implementation of VI & P services. In regards to the latter, these laboratories are responding in a flexible manner to the increasing diversity and disposal of the communications environment by separating the network into a transmission system and a versatile information control/conversion -ion system and laboratories are working at enhancing the performance of both. Within these board aims, the laboratories are currently focusing our attention in three areas : the technology for a high-speed broadband transmission system featuring optical frequency multiplexing and ATM techniques, network and software technologies for advanced information control and conversion, and technology for constructing a new access network that can provide a comprehensive range of multimedia services. This article describes the laboratories' concept of how VI & P services will develop in the future, and the latest trends in the field of communications. It also describes the ideal configuration of the new network and discusses the important technological aspects of how it is to be constructed. Finally, it presents the results of the laboratories'recent research which include some innovative work, point out the areas requiring future investigation.

The slow evolution of global magnetic fields and other dynamical processes in atmospheres of CP magnetic stars lead to the development of induced electric currents in all conductive atmospheric layers. The Lorentz force, which results from the interaction between a magnetic field and the induced currents, may modify the atmospheric structure and provide insight into the formation and evolution of stellar magnetic fields. This modification of the pressure-temperature structure influences the formation of absorption spectral features producing characteristic rotational variability of some spectral lines, especially the Balmer lines (Valyavin et al., 2004 and references therein). In order to study these theoretical predictions we began systematic spectroscopic survey of Balmer line variability in spectra of brightest CP magnetic stars. Here we present the first results of the program. A0p star $\Theta$ Aur revealed significant variability of the Balmer profiles during the star's rotation. Character of this variablity corresponds to that classified by Kroll (1989) as a result of an impact of significant Lorentz force. From the obtained data we estimate that amplitudes of the variation at H$\alpha$, H$\beta$, H$\gamma$ and H$\delta$ profiles reach up to $2.4\%$during full rotation cycle of the star. Using computation of our model atmospheres (Valyavin et al., 2004) we interpret these data within the framework of the simplest model of the evolution of global magnetic fields in chemically peculiar stars. Assuming that the field is represented by a dipole, we estimate the characteristic e.m.f. induced by the field decay electric current (and the Lorentz force as the result) on the order of $E {\~} 10^{-11}$ cgs units, which may indicate very fast (< < $10^{10}$ years) evolution rate of the field. This result strongly contradicts the theoretical point of view that global stellar magnetic fields of CP stars are fossil and their the characteristic decay time of about $10^{10}$ yr. Alternatively, we briefly discuss concurring effects (like the ambipolar diffusion) which may also lead to significant atmospheric currents producing the observable Lorentz force.
