This study is to examine how Sijo is being accommodated to modern Gagok by comparing them. In details, the work is about comparison between three verses in Sijo and twofold grouping in modern Gogok, JoongYuUm in traditional Gagok, YuBak in Sijo, the interlude, ADanSungJang, and changing verses in modern Gagok. First point is about three verses in Sijo and a rhythm of twofold grouping in modern Gagok. In particular, modern Gagok is treated as a group of twofold leaving three verses of Sijo. The way is chosen that whether it sets on an interlude into a song or the third part of three verses in Sijo is extended to avoid its logic of music and poem. Second, the discussion moves points on between an interlude in traditional Gagok and in Sijo. In the process of grouping twofold in modern Gagok, the parts which are interludes of both in traditional Gagok and in Sijo, combined with the interlude of the modern Gagok. It shows that the modern Gagok is affected on both the traditional Gagok and the Sijo. In addition, it explains elements of ADanSungJang - - tones and sounds in the modern Gagok. Originally, the traditional Gagok and sijo are composed of tones and sounds. At this point, tones are short, whereas sounds should be longer. This kind of way in the song has appeared on the modern Gagok of Hong, Nan-Pa. Lastly, the factors is about changing verses of modern Gagok. The one of differences between the modern Sijo and traditional Sijo is verses. For example, when it comes to sijo by Lee, Eun-Sang, he used to create his sijo with three verses. Hence, he did not change verses on his works. Whereas, the modern song "The Spring Lady" by Hong, Nan-Pa has shown the phenomenon that is separating three verses into six verses. It is noticeable that this phenomenon in "The Spring Lady" has the same bases with the modern Sijo.

Recently, I presented Gagok(歌曲) Collection Yeong-eon永言 to learned circles. Yeong-eon is very similar to Yukdang-version六堂本 CheongGuYeongeon靑丘永言. Compared with Cheong- Yuk, it is the same age or little bit early time of Cheong-Yuk in culture Icon. This paper paid attention to the considerable difference between Yeong-eon and Cheong-Yuk in the way of the distribution of Yisakdaeyap二數大 葉's Woo mode羽調 and Ke-myeon mode界面調. There was the way of gathering ‘real name’+‘namelessness’ in Yisakdaeyap, which is the feature of the 18th century Gagok Collection. I found this way just put on the 19th century Gagok Collection way which is the distribution of Yisakdaeyap's 'Woo mode and Ke-myeon mode' in CheongYuk. Then I proved in this paper that the way of gathering Yisakdaeyap in Cheong Yuk didn't correspond to an actual singing in the early 19th century when 'Woo mode and Ke-myeon mode' was fixed. In case of Yeong-eon, however, it was not written any writers' names at all, when it was researched retroactively, I knew it was distributed evenly both the works of 'real name' and 'namelessness' in Yisakdaeyaps 'Woo mode and Ke-myeon mode'. Consequently, I found Yeong-eon is the good Gagok Collection for an actual singing at that time. In addition, there was discord in the mode or key distribution among many Gagok Collections. I found this issue of the application had kept on make Gagok Collections edit during 2 centuries. Because the actual Gagok enjoyment in the specific time is connected the way of the mode application directly.

This paper's target is two music books, 100 man's Gagok songs and 88 woman's Gagok songs compiled by Kim Kee-soo. The next is an interpretation on 9 subject classifications. 1. There is a similiarity in subject between $\lceil$kyobonyukdaesijo's collection$\rfloor$ and man's Gagok song. 2. There is a wide difference in man and woman's love subject between man's Gagok songs and woman's Gagok songs. 3. The subject changes as Gagok progreasses. 4. There are many nameless writers in the prograss of Nong$\cdot$Na k$\cdot$Peon. 5. Taepeongga, whose theme is to enjoy pleasure, forms the last beauty. Sijo poem's subjects, which belongs to the noble class, shows the mode of scholar's elegant life at that time.

Shijo (Korean poetic form) is a representative literature genre of a short poem among the literary works of Korea in the late Chosen Dynasty. The format of Sijo is Normal-Shijo in the form of 3 verses, 6 sections and 12 sound, and the lyrics of one Normal-Shijo has within or without 45 words. But Saseol-sijo, a type of Sijo, there is a work that has more than 100 letters due to the number of lyrics were a lot increased. Among those Saseol-sijo there is a work with 'solemn and elegant feeling' borrowing some verses even from Chinese poem, using a lot of Chinese vocabulary, but there are a lot of works with 'salacious and explicit contents'. Literary work, Shijo, is used for lyrics of vocal music as Gagok (a genre of Korean vocal music for mixed female and male voices) and Sijochang, however, there are many cases that the same Sijo poem is used as lyrics of Gagok and Shijo. But those music that use Saseol-sijo as lyrics among Gagok, the vocal music, are mainly songs with 'solemn feeling' rather than 'salacious work'. This study looked into the reason why the Saseol-sijo with 'salacious and explicit contents' are hard to be used as lyrics in Gagok, confirming the fact that most music singing Saseol-sijo among Gagok that are being handed down till now use lyrics with 'solemn and elegant feeling'. The most important thing among those reasons seems to be irregularly increasing lyrics, and in accordance with accompaniment. Gagok accompanys a number of instruments the fixed melody recorded and delivered in score. So it's almost impossible to play unless it depends on the steadily made song melody and accompaniment melody according to the chosen lyrics in advanced. Also, appreciation of literary works is usually made privately through a private reading activity, but Gagok is conducted through public performance in an open space for many people. Especially, it would have been hard to sing a salacious and explicit song gathered together with men and women of different social status in social system and custom of the late of Chosen Dynasty. This study confirmed the fact that folksy and popular character that was praised for literary characteristic of Saseol-sijo can't be easily found from Saseol-sijo that was called Gagok.

'Geumokchongbu' that is Gajib(a book of songs) is composed only the works of An Minyoung. Ahn Minyoung was not only an editor of Gajib and also Musician that is a kind of singer, Because of his works, he is the one who should be studied for the history of literature of Sijo in the latter period of Chosun, especially in 19th century. Through the studies on 'Geumokchongbu' that is the Gajib edited by Ahn Minyoung. his excellent musical talent could be confirmed. 'Geumokchongbu' which is another Gajib in compared to 'Gagokwonryu' was produced under his careful musical consideration. The tunes shown on Gajib reflected the situation of Gagok just as it was sung and played in that period. Generally, the system of Gajib which was edited in that period Including 'Geumokchongbu' was continued on nowaday's tradition of singing and playing the Gagok. Nevertheless lots of studied results about Ahn Minyoung, the editor of Gajib. was reported. his personal aspect still was not explained for many detailed part. The introduction o( the background of works and various explanation was recorded for each work in 'Geumokchongbu'. The written year of works was found in the introductions. and some of Ahn Minyoung's life could be traced through the chronicle. It could be confirmed for his broad knowledge about music and detailed reality of active correspondences with many loyal family including Daewongun, Lee Haeung and artists in that period. The existence of a type of singing and playing which takes any part of specific tunes shown on Gajib was confirmed. For example, Hachuksi, a blessing poem, dedicated for Daewongun or loyal family was created for supposing singing and playing thoroughly. Accordingly, Hachuksi dedicated to specific persons might be sung and played at the same place, and in the same bundle. Through the study, the way of singing and playing the Gagok was much various, and the variety was confirmed concretely.

In order to develop an effective mineral exploration technique, this study was carried out about the potential mapping of Gagok mine. The deposit model of Gagok mine is widely known. Based on the deposit model, we constructed mining indicator indices using related igneous rocks, faults, and carbonate rocks. By analyzing the spatial correlation between ore and indicator index structures, we decided the weighting values of indices according to the distance from the index structure. The 3D potential mapping was performed using 3D geological model and geological indices. The analyzed potential map verified that the locations and patterns of high potential regions of the results were well matched with those of the known ore bodies. Using the potential mapping results, we could effectively predict the location of a high potential area that has similar geological settings with ore.

The time-dependent behaviour of rock is very important characteristics which can be utilized as basic input data for underground mine design or in predicting a long-term stability of underground rock mass structures. In this study, creep tests under uniaxial compression were carried out for the granite specimens sampled in Gagok Mine. Burgers model, Griggs and Singh creep laws were used to simulate the measured creep strain. Through comparing the measured creep behaviour with the approximated creep behaviors from Burgers model, Griggs and Singh creep laws, it is shown that Griggs creep law results in the best approximation of granite in Gagok Mine.

The Gagok stratabound skarn deposit is the result of the intrusion of the Cretaceous granitic pluton into the Paleozoic calcareous rocks. The subvolcanic intrusion ranges in composition from quartz monzonite to granite porphyry with I-type, calc-alkaline and weakly peraluminous characteristics. Both endoskarn and exoskarn are developed at the Gagok Zn-(Pb) deposit, with more exoskarn than endoskarn. Geochemical and mineralogical characteristics in the Seongok and Wolgok orebodies can be treated in terms of self-organization. Sphalerites in the Gagok ore can also incorporate minor amounts of Mn, Cd, Cu and In. Trace element concentrations in different orebodies vary because fractionation of a given element into sphalerite is influenced by formation temperature and the amount of sphalerite in the ore. A group of high In/Zn and Cd/Zn ratios in ores, and low Mn/Fe ratios in sphalerites are correlated with proximal processes of a magmatic source. The pattern of minor/trace element variations in ores and sphalcrites can be used for petrogenetic interprctation, e.g., orebody zonation related to crystallization temperature and fluid d sources.
