In religious studies, soteriology is a belief system that aims to compensate and solve the existential suffering of human beings through a doctrinal system of healing, liberation, and salvation as advocated by various religions. The purpose of this study is to understand the soteriology of Dasesoon Jinrihoe, a Korean new religion, and to understand its characteristics. The soteriology of Daesoon Jinrihoe is closely related to the theory of The Reordering Works of Heaven and Earth. The Reordering Works of Heaven and Earth is a doctrinal system in which the Supreme God, Jeungsan, was incarnated into a human body to rescue the world and creation and to achieve this, he had performed various religious works. In addition, the soteriology of Daesoon Jinrihoe is linked to the theory of orthodox lineage spanning Jeungsan to Jeongsan and lastly to Udang. The work of salvation performed by Jeungsan is settled by Jeongsan who systematized it into methods of practice. This soteriology has distinctive differences separating it from traditional religious traditions. First, it shows the characteristic of offering salvation through a supreme, personal God. Second, Jeungsan is seen as having changed the cosmic law and provided the basis for the world and creation to be saved. Finally, it proposes a theory that saving the world and creation is to be achieved through the principle of the Resolution of Grievances.

This paper is an attempt to find commonality and complementarity between psychanalysis and Daesoon thought, while understanding the practical meaning of the Haewon-Sangsaeng, which is one of the religious doctrines of Daesoon Jinrihoe, in terms of the theory of desire posited by psychoanalysis. There is a common point between Daesoon thought and psychoanalytic theory since both ideas give importance to desire. The Haewon idea is similar to that of psychoanalytic theory, which emphasizes restoring desire through mourning and realizing it within a structure of inter-subjectivity. Of course, the meaning of desire in Daesoon thought, given its status as a religious doctrine, is polysemous, and the orientation of this type of desire is also different from that of psychoanalysis given psychoanalysis's role as a therapeutic discourse. However, Daesoon thought explains that the pain and unhappiness suffered by human beings occurs because of mutual overcoming which is a relational style wherein desire can not be solved properly for either party involved in an interaction. Mutual overcoming is a state of mutual beneficience beyond the previous state of mutual overcoming. Likewise, psychoanalysis seems to accept the loss of the object through mourning, and in this way, desire is reactivated. Daesoon thought emphasizes the importance of social and cosmic systems like mutual beneficience and the reordering of the Universe and these systems have a commonality with psychoanalysis as psychoanalysis sees desire positively within the structure of inter-subjectivity. The direction of social practice in Daesoon thought and psychoanalysis both aim at the realization of a new universality. The inter-subjectivity structure suggests desire of recognition and recognition of desire as a way of practice because desire is not personal but rather social. In conclusion, we should not stop at resolving our own individual desires, but should instead go forward in solidarity toward the achieving the common good.

The purposes of this treatise are to compare theories of theatre in 'Kwandaega' with theories of theatre in 'Poongjahwajun', to recognize differences of theories between the former and the latter, and to find out the comparative characteristics of theories of Korean theatre. There are four differences between the former and the latter. These are as follows; Firstly, in the aspect of contents, the former is consisted of discussions about nature of theatre, discussions about acting, discussions about staging, and the latter is consisted of discussions about nature of theatre, discussions about acting, discussions about staging, discussions about origin, and discussions about dramaturgy. Secondly, in the aspect of nature, the nature of theatre in the former is recognition and practice as 'homo performans', the nature of theatre in the latter is realization of 'flower[花]'. Thirdly, in the aspect of acting, discussions about acting of the former are consisted of 'Sachae' theory'(Inmulchirae, Sasulchirae, Dekm, Nerumsae), discussions about acting of the latter are consisted of method of training per ages, method of training per role playings, trainings in everyday life. Fourthly, in the aspect of staging, the focus of staging in the former is realization of an endless series of changes[千變萬化], the focus of staging in the latter is realization of 'flower[花]'. There are four characteritics in the theories of Kwangdaega. These are as follows; Firstly, the contents of kwangdaega are consisted of discussions about nature of theatre, discussions about acting, discussions about staging. This theory is theory centered on actor/actress. Secondly, the nature of thestre in Kwangdaega is recognition and practice as 'homo performans', supporting of self-generational values, supporting of folk, new interpretation about secularism. Thirdly, the discussions about acting are consist of 'Sachae Theory'. Fourthly, the discussions about staging are consisted of realizations of an endless series of changes[千變萬化]

Carbon fiber(CF) with excellent thermal conductivity and electrical conductivity is attracting attention as an alternative material because metal heating elements have problems such as high heat loss and fire risk. However, since CF is oxidized and disconnected at about 200℃ or higher, the application of heating elements is limited, and CF heating elements in the form of vacuum tubes are currently used in some commercial heaters. In this work, polyimide(PI) with high heat resistance was coated on the surface of carbon fiber by electrophoretic deposition to prevent oxidation of CF in the atmosphere without using a vacuum tube, and the coating thickness and heat resistance were investigated according to the applied voltage. The heater made by connecting the PI-coated CF heating elements in series showed stable heating characteristics up to 292℃, which was similar to the heating temperature result of the heat transfer simulation. The PI layer coated by the electrophoretic deposition method is effective in preventing oxidation of CF at 200℃ or higher and is expected to be applicable to various heating components such as secondary batteries, aerospace, and electric vehicles that require heat stability.

Monitoring technology based on electrical resistivity is widely used for non-destructive data collection and health analysis of underground structures and tunnels. Vulnerable sections such as fault zone generates many problems during construction of the tunnel. These problems cause displacement and stress changes of the ground. Therefore, it is necessary to predict the state of the fault zone section to ensure the mechanical stability of the underground structure. Monitoring the size of joints and the porosity of the fillings is essential for rocks. Previous studies have not considered the variety of fillings in rock joints. In this study, electrical resistivity tests were conducted according to the particle mixing state of the sandy fillings. When the size of fillings is decreased at the constant porosity, the electrical resistivity tends to increase. The results of this study are expected to be useful as basic electrical resistivity data for predicting the ground conditions and evaluation of the ground behavior that is containing sandy fillings in the rock joint for tunnels.

Smoke masks have attracted great interests and have been supplied widely for the improvement of the safety during fire evacuation. However, there is not sufficient research on the practical utility, certification status and easy-donning about commercial smoke masks, therefore it is difficult to determine the actual usefulness of the smoke masks. In this study, we conducted a survey on users' perceptions and experiences about the smoke masks, and investigated the status of certification of 54 commercial smoke masks. We also performed donning tests and examined degrees of discomfort for 4 types of the smoke masks. Although 22% of 235 respondents had experienced the smoke masks before the test, and 23% of the respondents did not know the smoke masks, 93% of the respondents expected that the smoke masks could protect users from fire smokes and toxic gases. It was found that 41% of the commercial smoke masks did not certify according to domestic or overseas performance standards. Most certification standards have not effectively regulated maximum wearing time for the smoke masks. Only ASTM E 2952 and KFIS 024 had specific standards for the maximum wearing time of 30 s. As a result of donning tests for 4 types of smoke masks, the wearing time of the hood-type mask and self-contained smoke mask exceeded 30 s, therefore these types of smoke masks might increase the required safe evacuation time. On the other hand, it was also found that short education about the donning could reduce the wearing time by 19% and numbers of improper wearing by 89%.

In this study, coffee waste was recycled into nitrogen-doped porous carbon fibers as an active material for high-energy EDLC (Electric Double Layer Capacitors). The coffee waste was mixed with polyvinylpyrrolidone and dissolved into dimethylformamide. The mixture was then electrospun to fabricate coffee waste-derived nanofibers (Bare-CWNF), and carbonization process was followed under a nitrogen atmosphere at 900℃. Similar to Bare-CWNF, the as-synthesized carbonized coffee waste-derived nanofibers (Carbonized-CWNF) maintained its fibrous form while preserving the composition of nitrogen. The electrochemical performance was analyzed for carbonized coffee waste (Carbonized-CW)-, carbonized PAN-derived nanofibers (Carbonized-PNF)-, and Carbonized-CWNF-based electrodes in the operating voltage window of -1.0-0.0V, Among the electrodes, Carbonized-CWNF-based electrodes exhibited the highest specific capacitance of 123.8F g^-1 at 1A g^-1 owing to presence of nitrogen and porous structure. As a result, nitrogen-contained porous carbon fibers synthesized from coffee waste showed excellent electrochemical performance as electrodes for high-energy EDLC. The experimental designed in this study successfully demonstrated the recycling of the coffee waste, one of the plant-based biomass that causes the environmental pollution into high-energy materials, also, attaining the ecofriendliness.

Recently, following the development of LIDAR technology which can detect distance from the object, the interest for LIDAR based 3D object detection network is getting higher. Previous networks generate inaccurate localization results due to spatial information loss during voxelization and downsampling. In this study, we propose an attention-based convergence method and a camera-LIDAR convergence system to acquire high-level features and high positional accuracy. First, by introducing the attention method into the Voxel-RCNN structure, which is a grid-based 3D object detection network, the multi-scale sparse 3D convolution feature is effectively fused to improve the performance of 3D object detection. Additionally, we propose the late-fusion mechanism for fusing outcomes in 3D object detection network and 2D object detection network to delete false positive. Comparative experiments with existing algorithms are performed using the KITTI data set, which is widely used in the field of autonomous driving. The proposed method showed performance improvement in both 2D object detection on BEV and 3D object detection. In particular, the precision was improved by about 0.54% for the car moderate class compared to Voxel-RCNN.

Experimental investigation on heat transfer ratio was firstly performed with three types of sandwich panels such as the Carbon/Epoxy Skin-Aluminum Honeycomb and Balsa Core Sandwich Panel of 37mm thickness, the Carbon/Epoxy Aluminum Skin-Honeycomb Core Sandwich Panel of 57mm thickness (including insulator) and the Carbon/Epoxy Skin-Aluminum Honeycomb Core Sandwich Panel of 37mm thickness based on the KS F 2278:2003(Insulation test method of windows). In additional to this investigation, experimental tests were also done for evaluation of heat transportation ratio with the Aluminum Skin- Aluminium Honeycomb Sandwich Panels of 27mm and 35mm thickness, and Aluminum Skin-Foaming Aluminum Sandwich Panel of 27mm thickness by the KS F2277:2002 (Insulation measuring method of construction component-Calibration heat box method or protective heat box method). In this study, it was found that the larger net heat transfer cross sectional area between the skin and the sandwich core is given, the higher heat transportation ratio occurs. It was also found that the hybrid type insulation had better insulation characteristics compared to the non-hybrid type insulation.

The Naedeokri and Nonggeori granites are early Proterozoic granites of the Taebaek-Sangdong area in the northeastern part of the Yeongnam Massif. In this paper, rare earth elements (REEs) concentrations of the minerals in Naedeokri and Nonggeori granites and Rb-Sr mineral isochron age are reported. Except zircon, the constituent minerals such as mica, feldspar, quartz, and tourmaline show LREE-enriched and HREE-depleted REE patterns with relatively large Eu negative anomaly. However, zircon has geochemical characteristic of LREE- and HREE-enriched REE pattern with large Eu positive anomaly. This pattern suggests that zircon should be hydrothermal zircon due to deuteric hydrothermal alteration. In addition, the Rb-Sr mineral age of Naedeokri granite indicates an age value of 1.814±142(2σ) Ma. The Rb-Sr whole rock age including pervious data of Naedeokri and Nogggeori granite indicates an age value of 1,707±74(2σ) Ma. This value is younger than the Sm-Nd isochron of 1.87 Ga, indicating that the Rb-Sr isotope system may be re-homogenized by hydrothermal alteration during the transition from a magmatic to a hydrothermal system.
