In the northern Cheongsong, there are occurred igneous intrusions: Cheongsong dike swarm, Jungtaesan laccolith, Galpyeongji stock. The swarm is composed of rhyolitic dikes that have developed many various spherulites. The dikes represent an geometrically radical pattern centering the Galpyeongji stock, but also geochemistry of the intrusions indicate the swarm source. Here we report the compositional data for 28 samples from the three intrusions. All of the intrusions belong to rhyolitic composition, but according to compositional correlation, there are considerable overlaps between intrusion compositions. In particular, the Cheongsong dike swarm is divided into several dike groups by rock color and shows compositional diversity, but the composition of the dikes generally overlap with compositions of other intrusions. The Jungtaesan laccolith is enriched in alkali, $K_2O$ and $Al_2O_3$ and depleted in $Fe_2O_3{^t}$, $TiO_2$ and REE compared to the Cheongsong dike swarm. In contrast, the Galpyeongji stock is narrow in composition range, and commonly has sharp compositional overlaps with the Cheongsong dike swarm. According to the compositional correlations, the stock is considered to be a source of the swarm and it is connected to an episode of volcanism.

In Cheongsong area, very rare spherulitic rhyolites both in Korea and foreign countries occur as dykes showing various types. The spherulites in them represent an undercooling caused by very fast cooling of the dykes in a shallow depth near to the surface and the variety of types were resulted from the difference of relative cooling rate. Cheongsong spherulitic rhyolites can be classified into five types; radiated simple spherulite, layered simple spherulite, layered multiple spherulite, radiated-layered multiple spherulite, radiating layered multiple spherulite. Radiated simple and radiating layered multiple spherulites formed by diffusion current caused by undercooling related to very fast cooling. On the other hand, layered multiple spherulites formed by relatively slow diffusion as a Liesegang ring during relatively slow cooling. If the cooling rate is between the two cases, layered simple spherulites formed. This interpretation indicates that Chrysanthemum, Dandelion, Dahlia and Sunflower types which are included in radiated simple or radiating layered multiple spherulites formed in the dykes with the fastest cooling rate in Cheongsong area while Peony, Rose and Innominate types classified as layered multiple spherulite formed in the dykes with the relatively slowest cooling rate. At the cooling rate between them, Apricot type spherulite formed. The K-Ar age-dating for Cheongsong spherulitic rhyolites indicate them to be formed between 48 and 50 Ma. The Cheongsong rhyolites are very valuable for research and preservation because of their rarity, beauty and diversity.

Species of genus Acanthopanax(Araliaceae) are long-lived trees primarily distributed throughout East Asia. These species are regarded as medically and ecologically important in Korea. A variety of Cheongsong in Korea is one of these cultivated varieties, however this variety is much longer(>100 years) than those of other cultivated groups. The components of variety of Acanthopanax in Cheongsong were analyzed for the first time and were compared to those of all Acanthopanax taxa in Korea. Nineteen components were specific to variety in Cheongsong. The main components of this variety were $\beta$-caryophyllene, hexadecanoic acid and ethyl stearate. Although some components are differ from each other, variety Cheongsong was similar to A. senticosus at phonetic topology with content of the chemicals, In addition, six species of genus Acanthopanax were investigated to compare the major chemical components by GC-MS.

The Gilan-Cheongsong area, which is in contact with Yeongyang and Uiseong Blocks of Gyeongsang Basin, Korea, consists of Precambrian metamorphic rocks, Triassic Cheongsong granite, Cretaceous sedimentary rocks(Iljik, Hupyeongdong, Jeomgok Formations), and Cretaceous igneous rocks(andesite, quartz porphyry, felsite). In this area are developed faults trending in (W)NW, NNW, ENE, NS, (N)NE directions which are representative in the Gyeongsang Basin. We analyzed the geometric and kinematic characteristics of fracture systems to inquire into movement history and sense of these faults in this area. This study suggests that these faults were mainly strike-slip movement. The orientations of fracture sets show ENE, NNW, (W)NW, (N)NE, NS in descending order of frequency. Their prolongation presents (W)NW, NNW, ENE, (N)NE, NS in descending order of predominance, and also agrees with that of faults in this area. The development sequence and movement sense of fracture sets are summarized as follows; (1) (W)NW: dextral shearing $\rightarrow$ (2) (W)NW and NNW: conjugate shearing(the former: dextral, the latter: sinistral) $\rightarrow$ (3) NNW: dextral shearing $\rightarrow$ (4) (W)NW: sinistral shearing $\rightarrow$ (5) ENE: dextral shearing $\rightarrow$ (6) ENE and NS: conjugate shearing(the former: sinistral, the latter: dextral) $\rightarrow$ (7) (N)NE: sinistral shearing, and this result is closely associated with the development sequence and movement sense of faults developed in this area.

This study was carried out to analyze the nutritional composition, bioactive compound and antioxidant activity in fresh sprout of 3 new Kalopanax septemlobus cultivars. Cheong-San, Cheong-Song and Cheong Sun 1 had largest carbohydrate (52.90, 53.12, 55.28%), crude protein (34.23, 31.33, 33.58%) in the proximate composition and had largest K (2.29, 2.22, 2.23%) followed by Ca (0.44, 0.34, 0.37%), Mg (0.24, 0.19, 0.19%) in the mineral contents. Three new cultivars contained a total of 26, 25 and 28 different kinds of amino acids, respectively and the number of essential amino acid is 6, 6 and 7 species, respectively. Also, Cheong-San had higher total polyphenol contents and Cheong-Song had higher total flavonoid contents. DPPH free radical scavenging activity of 70% ethanol, water extracts of Cheong-San and Cheong-Song is higher than others at 100 ppm. In the ABTS radical cation decolorization activity, 70% ethanol extract of Cheong Sun 1, water extract of Cheong-San and Cheong-Song are higher activity than others and all samples have more than 85% ABTS racial cation decolorization activity at 500 ppm. Our results suggest that new K. septemlobus cultivars possess good antioxidant capacities with a high nutritional value and might have potential applications in the food and medical industries.

Jungtaesan and Galpyeongji intrusions in the northeastern Cheongsong occur as laccolith and stock which intrude Gasongdong Formation and Dogyedong Formation, respectively. Cheongsong dike swarm, intruding the Dogyedong Formation, is closely associated with this stock. The dike swarm is more radial to focus into Galpyeongji and its outline is oval. The dikes of the dike swarm are only rhyolite dikes with flow banded, spherulitic and rare stony structures, and represents a single intrusive phase of magma. It can be interpretated that orientation of the dikes is controlled by stress states. Therefore, the dikes display a radial pattern through occupying vertical joints that have been generally attributed to radial fractures formed during doming of the sedimentary rocks by the intrusion of the Galpyeongji stock. The dike pattern could sufficiently account for dike injections into these joints.

Depending on the class and status, literary works are variously accepted and interpreted. As a result, they show different forms and ways of enjoying the novels and different variations of a text. The only ideal way of investigating and analyzting it is to meet someone who actually lived in that era. This study tries to investigate the enjoying aspects of the classic Korean classical novels by studying how the classical novels have been enjoyed in Northern Gyeong-Buk Area, especially in Cheongsong. It is a follow-up study of cases studies based in Yeongdeok, Uljin. As a result, one can come true the conclusions. In the case of Cheongsong, the Northern Area and Southern Areas show differences in their modes enjoying the Korean classical novels. The Northern Area has a strong expresses self-confidence and pride, and forms solid enjoying groups. However I could hardly find any such cases in the Southern Area. And the entertaining aspects of the classical novels are enjoyed by individuals rather than entertainers. It shows that there have been many difficulties in the culture of in taking-root classical novels as a firm ludic culture in Cheongsong. Furthermore, this survey can identify a duality of entertainers genres conception to enjoying Ga-sa and classic the Korean classical novels. The entertainers who haves read only the classical novels has not hidden ashamed of themselves as readers and entertainersof them. But the entertainers who are proud of the self as enjoyers of Ga-sa tried to dissimulate hide the fact that they read of the classical novels, because they think that a narrativity and fictitiousness, incredibility of the novels are disproportionate inappropriate to their for dignity as members of Yangban(兩班) families, and are in stark contrast to the morality and seriousness of Ga-sa.
