This study aims to develop a restoration model of an armillary sphere of Tongcheon-ui (Pan-celestial Armillary Sphere) by referring to the records of Damheonseo (Hong Dae-Yong Anthology) and the artifact of an armillary sphere in the Korean Christian Museum of Soongsil University. Between 1760 and 1762, Hong, Dae-Yong (1731-1783) built Tongcheon-ui, with Na, Kyung-Jeok (1690-1762) designing the basic structure and Ann, Cheo-In (1710-1787) completing the assembly. The model in this study is a spherical body with a diameter of 510 mm. Tongcheon-ui operates the armillary sphere by transmitting the rotational power from the lantern clock. The armillary sphere is constructed in the fashion of a two-layer sphere: the outer one is Yukhab-ui that is fixed; and the inner one, Samsin-ui, is rotated around the polar axis. In the equatorial ring possessed by Samsin-ui, an ecliptic ring and a lunar-path ring are successively fixed and are tilted by 23.5° and 28.5° over the equatorial ring, respectively. A solar miniature attached to a 365-toothed inner gear on the ecliptic ring reproduces the annual motion of the Sun. A lunar miniature installed on a 114-toothed inner gear of the lunar-path ring can also replay the moon's orbital motion and phase change. By the set of 'a ratchet gear, a shaft and a spur gear' installed in the solstice-colure double-ring, the inner gears in the ecliptic ring and lunar-path ring can be rotated in the opposite direction to the rotation of Samsin-ui and then the solar and lunar miniatures can simulate their revolution over the period of a year and a month, respectively. In order to indicate the change of the moon phases, 27 pins were arranged in a uniform circle around the lunar-path ring, and the 29-toothed wheel is fixed under the solar miniature. At the center of the armillary sphere, an earth plate representing a world map is fixed horizontally. Tongcheon-ui is the armillary sphere clock developed by Confucian scholars in the late Joseon Dynasty, and the technical level at which astronomical clocks could be produced at the time is of a high standard.

This thesis is to investigate the effectiveness of Cinema Therapy through the aspect of vicarious learning, that is, Nayeoug's modelling after Yeonsun, and Yeonsun's modelling after The Little Mermaid, by making My Mother, the Mermaid directed by Park Heungsik. After immature Nayeoung returns from the travel into past time, she is reborn as an mature woman, and finally she can manage a happy marriage life. In Nayeoung's initiation, there is Yeonsun's initiation, in that again, there is a initiation of The Little Mermaid by Hans Christian Andersen. This work is a proper text in explaining the effectiveness of Cinema Therapy which aims at self-awareness and self-improvement because it contains some aspects of the vicarious learning through the movie. Nayeon's mother(Yeonsun), Nayeoung's father(Jinguk) have trouble, and sometimes have friendly relations. The major characters' wish and need are examined out through the analysis of the five basic needs based on reality therapy. As a result, it is found out that when their needs are fulfilled, friendly relation is formed, and when their needs are not fulfilled, unfriendly relation is formed. If their own basic desires are examined, their desires can be fulfilled through the inner control by themselves.

This study poses a question on whether the Jangmadang Generation, which has been the focus of the sociological interest, can form an actual generation by transcending the social classes, status of students, ethnicity, and gender, etc. Therefore, in this study, the author compared the consciousness of the Jangmadang Generation in terms of politics, education, society, compliance with law, and education with their preceding generations. The data used in this study were gathered from the North Korean defectors who defected within the past five years over the period from November to December 2016. A total of 200 questionnaires were used for data analysis, which was conducted using SPSS 20.0, in order to show differences between groups and perform frequency analysis. The analysis results showed that the consciousness of the Jangmadang Generation in politics, society, compliance, and education was lower, while the economic consciousness was significantly higher compared to earlier generations. As their objective generational status, the Jangmadang Generation had experienced the 'March of Ordeal' and 'Collapse of Public Education' while they were still teenagers. Such a difference in their generational status influenced the formation of different consciousness as a generation compared to the earlier generations. Compared to the earlier generations who received 'proper public education,' the Jangmadang Generation, who did not receive 'decent public education' shows a generally lower level of consciousness compared to the earlier generations. As such, the Jangmadang Generation has the potential to form a separate generation with a different generation consciousness from that of earlier generations.

The Cheondeok-Song (religious songs of Cheondo-Gyo) of the Japanese colonial period shown on Cheondo-Gyohwe-Weolbo, the monthly magazine of Cheondo-Gyo Church were examined in this paper. The results are as follows. There are scores of songs, lyrics, and articles related to Cheondeok-Song in the monthly magazine. The five-tone scale or Korean traditional rhythm style was partly used, but western music form was dominant in most of the songs. Especially the four-part form of Christian hymns became usual since 1931. This shows how people thought of the new trends. The reception of the new trends being emphasized, but they recognized tradition as an object of overcoming rather than of succeeding. The lyrics contain religious contents and the spirit of the period to restore national self-respect and contribute to the world peace through overcoming Japanese imperialism. But the rhythm of seven and five syllables which is suspected to have been introduced by Japan was spread after the 1920s. Cheondeok-Song have been sung in the three grand anniversaries and other anniversaries, the Prayer-day, in Cheondo-Gyo church services on Sunday, ceremonies, and in lecture. There are various kinds of songs and their status is very high. Especially, Cheondeok-Song have been used actively in mission works and edification for women. Cheondeok-Song actively reflected the domestic and international trends and the demands of that times. They could sing self perfection through enlightenment and also the social reform based on it. These are the reasons why I think Cheondeok-Song of those days are so important. Cheondeok-Song reflected modern elements actively, but couldn't succeed the national form and the traditional elements properly. The problem of cultural identity is not only a specific group's but also that of the whole humanity of maintaining cultural diversity. This is also a task that Cheondo-Gyo Cheondeok-Song have to solve in the future.

In this study, the researcher examined archaeomagnetic secular variation of Chungcheong Region through measured data of archaeomagnet obtained from 34 relics, which discovered in the baked earth from varied historic sites within the region. Furthermore, the researcher closely reviewed regional differences of geomagnetic field in the domestic territory. Reviewing the comparison between the measured data of archaeomagnet in Chungcheong Region and the archaeomagnetic secular variation of Japan, which has difference in distance, it reveals a noticeable change in declination by tilting more than 10 degree toward East in the year of about A.D. 300, although the feature of whole variation is quite similar. In other period of times, it was confirmed that the regional differences of geomagnetic field in which the magnetic dip became deeper to some degree, and the declination was tilted westward a little bit. Such patterns do not differ significantly from the pattern of entire archaeomagnetic secular variation of our country, and even in the direct comparison to the data of Chungcheong Region, the distinct regional difference in both periods before and after Christian era was not confirmed. The fact may become clearer that, when the volume of the measured data of archaeomagnet increases further, and when more data connected with varied time period are filled, the problem such as deviation of the measurement period of archaeomagnet caused by the regional difference of geomagnetic field would not be worrisome issue, especially in Korean territory, judging from the measured data of archaeomagnet of historic relics in Chungcheong Region. Besides, as great efforts are being exerted in order to get the most reliable measured data as much as possible in taking both samples and measurement, it is thought that there would be no problem not only in the issue of deviation of the measurement period involving with the measured data of archeomagnet, but also in the aspect of reliability of data.

The purpose of this paper is to create an inter-religious dialogue between the Western Christian concept of the spirit and Eastern ch'i philosophy within the category of panentheism. The Hebrew term ruah means 'moving air' and 'wind' which derive from the particular experience of the ancient Hebrew people living in the desert. The Greek pnuema also means 'life' and 'wind' which denote the natural power. Both ruah and pneuma consist of the main idea of the spirit exploring the symbol of relationality of the divine in Western tradition. Eastern ch'i philosophy indicates a vital force for keeping the body and soul alive, which is unconscious and spontaneous. Ch'i as a vital force constitutes cosmogony and cosmology with the constant movement of yin and yang. Yin and Yang as representing earth and heaven are dynamic breaths, blending harmoniously to become all existence. The ethical implication of the inter-religious dialogue between the spirit and ch'i would be the integration and interconnection of heaven, earth, and human beings. The dialogue suggests becoming one body with nature and human community through embodying the non-dualistic spirit of life. The inter-relationality means that since all modalities of existence are made of the cosmic life, human beings are part of the divine cosmic process. This is related to degree of spirituality in the entire chain of being: rocks, trees, animals, humans, and goods represent different levels of spirituality based on the varying composition of the spirit and ch'i. All beings that internally embody with the spirit and ch'i are organically inter-connected, and they are integral part of a continuous process of transformation of life towards holistic liberation of human and nature community.

The two religious ethics, Christianity's 'love your enemies' and Daesoon Jinrihoe's 'grievance-resolution for mutual beneficence', can be misunderstood as similar. The misunderstanding arises from these religious ethics having something in common that specifically points to a particular object, called an enemy, and contains instructions to treat that object altruistically. However, from the perspective of Religious Ethics, the two teachings are not the same. The beliefs they are based upon are different, the religious character they pursue is different, and their processes of obtaining legitimacy, logic, and implementation are different. The most distinct difference between these ethics is that the Christian ethic focuses on a victim's role whereas Daesoon Jinrihoe ethic emphasizes the roles of both victims and perpetrators. In case of 'love your enemies,' if a perpetrator turns away from a victim and believes that they would be forgiven for their sin, the victim is unlikely to practice the teaching 'love your enemies.' Accordingly, to avoid criticism over cases wherein love of an enemy is nothing but a shallow grace, the roles of the two sides should be more highlighted than that of the absolute being. As for grievance-resolution for mutual beneficence, this teaching encourages victims to resolve their grievance with a goal of mutual beneficence. The perpetrator should likewise resolve the grievances and grudges of their victim with the aim of mutual beneficence. Jeungsan especially stressed that perpetrators have to resolve 'Cheok (慼: the resentment and grievances that someone holds against the one who victimized them)' through the ethic of grievance-resolution in order for living well. In other words, 'the ethic of Cheok-resolution' is an ethic wherein the perpetrator also plays an important role in the implementation of grievance-resolution for mutual beneficence.

This study was to investigate the relationship of job stress, health status, and health promotion behavior, retention intention and to identify the influencing factors on retention intention of nurse in Emergency Room(ER). The subjects were 155 ER nurses working at 15 general hospital in Gwangju, Korea. The data were collected from October 15, 2020 to November 3, 2020. The result, there were negative correlation between job stress and health promotion behavior(r=-0.310, p=<.000), between job stress and retention intention(r=-0.220, p=.006), between health status, and health promotion behavior(r=-0.448, p=<.000), between health status and retention intention(r=-0.296, p=<.000), but there were positive correlation between job stress and health status(r=0.368, p=<.000), between health promotion behavior and retention intention(r=0.229, p=.004). Factors influencing retention intention were fatige and health status with R2 value 22.7%. Considering these results, it seems that important factors determining the retention intention of nurses in ER are Spiritual health status, heavy workload due to job stress, fatigue and social health status by nurse. Therefore, in order to increase the retention intention of nurse in ER, it is a need for strategies to improve the working environment and develop programs to reduce job stress and fatigue through work adjustment, and to maintain and promote health.

Fairy tales are rooted in folk tales and contain human unconsciousness and universal emotions. It also plays a role as original content in various narrative transformation works. Andersen's brings numerous signification through symbolic signs of red shoes, dance, and ankle amputation. Victor W.Turner's theory of social drama broadens the perspective of narrative analysis. In addition, this theory makes us realize the conditions of the social community required by society at the time. As a circular content, Andersen's shows the double entry narrative of growth as a woman and incorporation into the social community. In this process, the social conditions accepted and rejected are symbolically revealed. In Koo Byung-mo's novel , achromatic color and red color are contrasted. The red world is full of vitality and represents the meaning of human existence. Yoon Mi-kyung's fairy tale is divided into different characters from the girl's growth narrative and the outsider's entry into the women's society. This work accuses preconceived notions and prejudices against multicultural families and strangers.

For optimal image quality of computer tomography angiography (CTA), different iodine concentrations and scan parameters were applied to quantitatively evaluate the image quality characteristics of filtered back projection (FBP), hybrid-iterative reconstruction (hybrid-IR), and deep learning reconstruction (DLR). A 320-row-detector CT scanner scanned a phantom with various iodine concentrations (1.2, 2.9, 4.9, 6.9, 10.4, 14.3, 18.4, and 25.9 mg/mL) located at the edge of a cylindrical water phantom with a diameter of 19 cm. Data obtained using each reconstruction technique was analyzed through noise, coefficient of variation (COV), and root mean square error (RMSE). As the iodine concentration increased, the CT number value increased, but the noise change did not show any special characteristics. COV decreased with increasing iodine concentration for FBP, adaptive iterative dose reduction (AIDR) 3D, and advanced intelligent clear-IQ engine (AiCE) at various tube voltages and tube currents. In addition, when the iodine concentration was low, there was a slight difference in COV between the reconstitution techniques, but there was little difference as the iodine concentration increased. AiCE showed the characteristic that RMSE decreased as the iodine concentration increased but rather increased after a specific concentration (4.9 mg/mL). Therefore, the user will have to consider the characteristics of scan parameters such as tube current and tube voltage as well as iodine concentration according to the reconstruction technique for optimal CTA image acquisition.
