부산 동래지역 지열수에 대한 지화학적 진화과정을 밝히기 위하여 지열수, 지하수 및 해수에 대한 수리화학 특성과 이들의 연관성을 고찰하였다. 또한 심부환경에서의 지화학 특성을 규명하기 위하여 각종 이온지질온도계와 다성분 지질온도계를 적용하였으며, 동위원소특성과 함께 지화학 모델링을 통하여 심부환경에서의 온천수의 지화학특성을 밝히고자 하였다. 동래 지열수의 수리화학적 특성은 해수의 영향을 받아 높은 이온함량을 보이며 Na-Cl형을 보여준다. 지열수는 주변 지하수와의 크게 혼합된 양상을 나타낸다. 지화학 모델링에 따르면 지열수는 심부에서 약 5% 영향을 받은 것으로 추정된다. 즉, 심부로 순환하는 지열수가 해수와 혼합되며, 이들이 지열에 의해 가열되면서 광물의 용해 및 침전, 이온 교환반응 등 물-암석 반응을 거치면서 심부지열수를 형성하였으며, 지열수가 천부환경으로 상승하는 과정에서 동래지역 주변 천부지하수와 다양하게 혼합되면서 현재 동래온천수의 화학조성을 갖는 온천수를 형성하는 것으로 지열수의 진화 과정을 설명할 수 있다.

The northern extension of the Dongrae Fault is inferred to transect the Ulsan Fault in the Gueo-ri area, Oedong-eup, ~15 km SE of Gyeongju City, Gyeongbuk province, S Korea. We conducted geological and geophysical (magnetic, electrical resistivity, and frequency domain electromagnetic) surveys to identify the extent and orientation of the Dongrae Fault in this region. Through joint interpretation of the geological and geophysical data sets, we confirm the presence of the Dongrae Fault and determine its strike ($N14^{\circ}E$). The Dongrae Fault is thought to cross the Ulsan Fault near Ipsil Bridge in the Gwangeo-ri area. Geophysical surveying revealed a fault damage zone that widens to the south, with a typical width of >200 m. Geological field surveys did not delineate the geometry of the Dongrae Fault because alluvial deposits overlie the fault in this area.

The Dongrae thermal water area located at the southeastern marginal part of the Korean Peninsula is one of the oldest hot springs in Korea. The Dongrae thermal water shows Na-Cl type of water chemistry, whereas the shallow cold groundwater is Ca(-Na)-$HCO_3$ type. In this paper, we discuss the age of the Dongrae hot spring, i.e. groundwater cycle among meteoric water-surface water-shallow groundwater-hot spring water. The $^{87}Sr/^{86}Sr$ ratios of the thermal water in Dongrae area range from 0.705663 to 0.705688 and are lower than those of groundwater, surface water and rain water as well as aquifer bearing granite. These Sr isotopic signatures in the Dongrae thermal water indicate that the circulation rate between thermal water and current meteoric water including groundwater, surface water and rain water in the Dongrae area should be very slow. The $^{14}C$ age of the Dongrae hot spring water range from $1,271{\pm}36$ BP(before present) to $2,467{\pm}36$ BP whereas that of the shallow groundwater is $-495{\pm}33$ BP. This suggests that the period of groundwater cycle among meteoric water, surface water, shallow groundwater and hot spring should be more than 1,270 years. Then, it also indicates that the present Dongrae hot spring may be a mixed water between the old thermal water heated for at least 1,270 years and the present shallow cold groundwater.

In this study, Long-term change of water quality in Donrae Hot Spring was characterized using water quality data from 1922 to 2019. According to Mann-Kendall analysis and Sen's slope using long-term water quality data of Dongnae Hot Spring from 1922 to 2019, temperature, Ca, SiO₂, and HCO₃ show an increasing trend whereas EC, Na, K, Mg, Cl, and SO₄ show a decreasing trend or negligible trend. In addition, the water type of Dongnae Hot Spring stably belongs to Na-Cl type over time. The spatial distributions of water temperature and chemical constituents in 2004, 2009, 2014, and 2019 show variable patterns with showing some difference depending on sampling locations in different years. These results indicate that despite the long-term pumping of the hot spring water, the water quality is quite stable during the entire study period.

The purpose of this research is to investigate the possibility of creating new theatrical contents by performance anthropological approach. Today's traditional performing arts are historically descended and developed in the forms of Ahk, Hee, and Geuk. Among those, Dongrae-yaru is a traditional mask dance, handed down in Dongrae, Pusan and appointed as the 18th intangible cultural asset. Its performance is carried out in the juxtaposition of Ahk, Hee, and Geuk. Korean theatre in the 21st century seems going back to realism after going through post-modern cultural phenomenons. However, the quest for alternative theatre is raised higher than ever. As a part of this strive, this paper asserts the traditional performing arts should be investigated as an alternative and new theatrical form. Among those traditional performing arts, Dongrae-yaru is selected for its well balanced combination of Ahk, Hee, and Geuk. The study examines in depth how each element of Ahk, Hee, and Geuk, they are expressed in forms of folk music, refined dance, jest, satire, wit. Its investigation on the stage adaptation provides the possibility for the new style and codification as the new theatre contents.

The Dongnae Fault in the southeastern part of the Korean Peninsular is not a single fault but a complex fault zone composed of numerous minor faults. In order to deduce the paleostress tensor evolving the Dongnae Fault, we measured 329 faults in outcrops around the fault zone and analyzed the geometries of them. Most of them are steeply dipping(>65˚) and fall into three groups striking N10E, N30E and N70E. More than one half of them show the rakes less than 30˚ Paleostress tensor analysis using the collected fault data has been conducted with the Angelier's direct inversion method and the Choi's method. As result, four different principal paleostress axes each of which subtends an independent tectonic event are found. They are; (1) NNE-SSW compression and ESE-WNW extension (Event I), (2) NNE-SSW extension (Event II), (3) ESE-WNW extension (Event III) and (4) ENE-WSW compression and NNW-SSE extension (Event IV) in chronology. Therefore, the tectonic movement around the Dongnae Fault was firstly governed by strike-slip faulting related to Event I. Afterward, normal faults were formed by Event II and Event III. Finally, the dextral strike-slip faults along the major trace of the Dongnae Fault were formed in NNE direction related to Event IV.

This thesis studied about the expression of the conflict in DongraeYaroo. Study perspective was time and passion. Time refers to a change in the time to move to the current from the past. As in the study was the change in the phase and values of the characters occurred. Passion is an act which is scheduled departing from the spirit moves the body. And the emotions move the human heart. And it was associated with the inner values that determine the ethical life. DongraeYaroo should ever criticize feudal era and values through the conflict with the changes in time. Through conflict with the realism tendencies and passions were melodramatic tendencies. DongraeYaroo is a folk masques of realism and melodramatic nature complex. DongraeYaroo has a part that is causing the conflict with the contents of the passion associated with the character's sexual desire is elsewhere. There are also distorted passions and inde normal expression of tragic passion passions that lead to death.
