This article explores the intersection of freedom of religion, sangsaeng, and symbiosis when considering the post-COVID study of religions, especially new religions. When it comes to the study of new and alternative religious groups, where there is more potential for misunderstanding and misinformation, it becomes all the more important-and indeed mutually beneficial, in the areas of religious liberty, religious freedom, and cross-cultural dialogue-to learn about a tradition by taking into account the spiritual life and practices of members themselves and their own sacred writings and practices. Daesoon Jinrihoe offers a case study of the importance of this principle and the notion of sangsaeng in particular is a fruitful utilitarian lens for thinking about how scholars, journalists, and others might approach the study of religion in our complex and global digital age of (mis) information. Daesoon Jinrihoe is also considered in light of Roy Wallis's typology of world-rejecting, world-affirming, and world-accommodating new religious movements. Open areas for sociological research are proposed and the nascent field of Daesoon studies is compared to some similar scholarly endeavors within NRM studies.

Korean religionist have actively participated in the movements of national security and peace, human rights and dignity, freedom and equal rights, and other social issues. Recently, either progressive or conservative religionists have strongly shown their different approaches in solving social issues, i.e., national security and peace in connection of 'national security law.' A few religious leaders' public views have been misused by some politicians. It is important for both the religionists and journalists in religious newspapers how to bring a harmonious resolution among the people who are either in conservatism or in progressivism. Social participation of religionists is both to respond to the timely situation of civil society and to realize freedom, equality, and peace to the society. Although the principle of the separation of religion and state was established to secure both the right of politics and the freedom of beliefs, political groups have either utilized or suppressed religions. Some politicians have also wrongly applied separation of religion and state by excluding religious aspects in public schools. Religionists and journalists of the religious newspapers should not provide one-sided prejudice but to provide objective information and its righteous analysis to guide people in the right direction to solve social problems. Also, religious newspapers should open a field of discussion how to resolve some issues between the 'national security law' and freedom.

Adaptive array systems are hard to remove all the interferences when incident signals are coherent with a desired signal. In this paper, we propose a modified Duvall beamformer, which performs spatial smoothing using spatial interpolation technique to maintain the degree of freedom. The propose algorithm can minimize the loss on the degree of freedom due to spatial smoothing by forming subarrays with interpolated signals. Simulation results show that the proposed algorithm can remove all the interferences while conventional beamformer cannot.

The number of measured degrees of freedom for detecting the damage of any structures is usually less than the number of model degrees of freedom. It is necessary to expand the measured data to full set of model degrees of freedom for updating modal data. This study presents the expansion methods to estimate all static displacements and dynamic modal data of finite element model from the measured data. The static and dynamic methods are derived by minimizing the variation of the potential energy and the Gauss's function, respectively. The applications illustrate the validity of the proposed methods. It is observed that the numerical results obtained by the static approach correspond with the Guyan condensation method and the derived static and dynamic approaches provide the fundamental idea for damage detection.

We propose a new design method for a generalized predictive control (GPC) system based on the parametrization of two-degree-of freedom control systems. The objective is to design the GPC system which guarantees the stability of the control system for a perturbed plant. The design procedure of our proposed method consists of three steps. First, we design a basic controller for a nominal plant using the LQG method and parametrize a whole control system. Next, we identify the deviation between the perturbed plant and the nominal one using a closed-loop identification method and design a free parameter of parametrization to stabilize the closed-loop system. Finally, we design a feedforward controller so as to incorporate GPC technique into our controller structure. A numerical example is presented to show the effectiveness of our proposed method.

Multi-degree-of-freedom (MDOF) displacement measurement Is needed In many application fields: precision machine control, precision assembly, vibration analysis, and so on. This paper presents a new MDOF displacement measurement method using a laser diode (LD), two position-sensitive detectors (PSDs), and a conventional diffraction grating. It utilizes typical features of a diffraction grating to obtain the information of MDOF displacement. MDOF displacement is calculated from the independent coordinate values of the diffracted ray spots on the PSDs. Forward and inverse kinematic problems were solved to compute the MDOF displacement of a rigid body. Experimental results show maximum absolute errors of less than ${\pm}10$ micrometers in translation and ${\pm}30$ arcsecs in rotation.

A new end-effector has been devised and the problems resulted from using it with SCARA robots are discussed. The end effector has two modules: one composed of two ultrasonic motors and two encoders for controlling each finger, and the other module composed of two ultrasonic motors and two encoders for controlling the wrist. The wrist module adds two degrees of freedom to the SCARA type robot, which generally has four degrees of freedom. With independent finger actuation and touch sensors, the gripper under computer control can feedback information about part size and part presence. Ultrasonic motors with high torque and slow motion characteristics are used. The principle of ultrasonic motors is explained and the servo characteristics of ultrasonic motors are studied. They are controlled by the general motion controller (Hewlett Packard HCTL-1000) which is linked to an IBM-PC AT.

With the advent of digital media environment, distribution way of information changes, legalization of the right to be forgotten is becoming increasingly necessary. However, too much emphasis on protection of personal information to hinder the development of the Internet industry and constitutional rights, including freedom of speech and right to know might be infringed. Thus, the scope of the right to be forgotten there is a need to clarify the rules. First, the rights of personal information can be divided into two. Right to be forgotten can be applied to the right to self-determination of personal information, but the right to self-determination information about social personality cannot be applied to. Second, in the digital media environment, old news article over the internet repeatedly distribution as the new damage is generating. Because old news article is a historical record, the right to be forgotten can not be applied. Thus, appropriate for digital media environment must find new ways.

In this paper, the optimal extended homotopy analysis method (OEHAM) is introduced to deal with the damped Duffing resonator driven by a van der Pol oscillator, which can be described as a complex Multi-Degree-of-Freedom (MDOF) nonlinear coupling system. Ecumenically, the exact solutions of the MDOF nonlinear coupling systems are difficult to be obtained, thus the development of analytical approximation becomes an effective and meaningful approach to analyze these systems. Compared with traditional perturbation methods, HAM is more valid and available, and has been widely used for nonlinear problems in recent years. Hence, the method will be chosen to study the system in this article. In order to acquire more suitable solutions, we put forward HAM to the OEHAM. For the sake of verifying the accuracy of the above method, a series of comparisons are introduced between the results received by the OEHAM and the numerical integration method. The results in this article demonstrate that the OEHAM is an effective and robust technique for MDOF nonlinear coupling systems. Besides, the presented methods can also be broadly used for various strongly nonlinear MDOF dynamical systems.

This paper presents a simple two-degree of freedom PID tuning table based on the CDM design method. The structure of the control system will be composed of plant, P or PI or PID controller and a pre-filter. The finalized formula can be used based on the experimental test of the plant in the same manner as the Ziegler-Nichols' second method. That is; users just need to find the critical gain and critical period experimentally and the parameters of the P, PI or PID controller with the pre-filter can be obtained by substituting the values of critical gain and critical period in the tuning table. The simulation results of the control systems utilizing the proposed controllers compared with those using the Ziegler-Nichols' second method will also be demonstrated.
