New thornless cultivar of castor aralia(Kalopanax septemlobus Koidz.) was developed and selected in Cheongsong, Prov. of GyeongSangbuk-do during the period from 1994 to 1999 by Korea Forest Research Institute(KFRI). The new thornless cultivar, "Cheongsong II" is characterized by a thinner outer-bark and soft, wider leaves, and is particularly characterized by thornless stems. This cultivar has a thinner outer-bark(8.82mm) when compared with thorned type trees(13.95mm). It also has a larger leaves than does thorned type trees. Consequently, the new thornless cultivar, "Cheongsong II" is defined to have thinner bark and longer and wider leaves than do other thorned type trees. thorned type trees.

Rural tourism is primarily a domestic tourism activity with visitors traveling to non-urban area. Therefore, local agricultural and special products as one of rural amenity resources have been used revisitation carriers of rural tourism. For these purpose, this study selected Cheongsong-gun in Gyeongsang province, which has been famous for Cheongsong apple and planned space program on that sites as on-farm research. The sites are divided into 6 districts, agricultural production, leisure, cultural space, events or festival, green space, infrastructure for local residents and tourists. Above all, this study led local government to develop related policies using local agricultural and special products, which can be an example to plan for regional development.

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.

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.

The purpose of this study is to measure the levels of eluted and dissolved CO2, and CO, volatile organic substances and radiation composition of Cheongsong mineral water which were collected from November 2019 to July 2020 during the autumn, spring, and summer seasons at collection points located in the upper, middle and lower spring waters. Data of the upper, middle and lower spring waters include the following: the amount of eluted water (average value±standard deviation, mL/min) was 30.07±0.52, 15.03±0.16, 23.73±0.42, and the amount of CO2 gas was 1,000 ppm or more. In addition, there was no detection of CO or total volatile organic substances (TVOC) and the radiation dose was 0.08 to 0.13. μSv/h. A blank test value of 0.08 to 0.10 μSv/h, when compared with the median value, showed a high value of 0.02 μSv/h, and the uranium test results provided by the Cheongsong-gun Office were 0.0118 mg/L (date 2019.06.18) and 0.0091 mg/L (date 2020.06.04.) respectively, which was less than the permission limit of 0.03 mg/L. However, it is believed that further research using more precise devices is needed in order to guarantee the safety and health of the water.

This study aimed to plan a distinctive apple theme park, thereby specializing the nationwide brand of Cheongsong apple. Detailed objectives included: to establish the best possible environments in Korea to taste and appreciate apple and enjoy the Cheongsong Apple Festival; to identify and foster natural, cultural and social resources in the clean environment of Cheongsong; to clusterize research and production infrastructures for strengthening local competitiveness; and to develop a hub for the vitalization of the region where visitors and locals can mutually prosper. The study was multi-phased. The first stage included basic surveys such as local status and environment analysis and similar case studies, and the second stage was to review the appropriateness of theme selection, develop basic principles and strategies for development goals and review and incorporate project details. And the third stage aimed to develop a comprehensive plan from spatial plans and program plans and suggest plans to vitalize the operation of the park. The dimension of the subject site was $180,150m^2$, which was divided into four areas, in consideration of the land use and the environmental characteristics of the resources, for developing a land use scheme. The four areas were named: the apple-theme cultual area; the agricultural culture experience area; the plaza for exchange and harmony; and the plaza for natural observation. This study has significance in that it can serve as a case to develop farm theme parks, and as a case of appropriate development of programs to identify amenity resources with a focus on the existing resources and in consideration of local characteristics.

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.

The infection status with Clonorchis sinensis metacercariae (CsMc) was examined in freshwater fishes from Yongjeon-cheon (a branch of Nakdong-gang) located in Cheongsong-gun, Gyeongsangbuk-do, the Republic of Korea (Korea). A total of 750 fishes in 19 species were examined by the artificial digestion method for 2 years (2019 and 2020). CsMc were detected in 378 (51.4%) out of 735 fishes in 14 species (73.7%), and the infection intensity was 666 per fish infected. In 2019, CsMc were found in 172 (68.0%) out of 253 fishes in 10 species, and the infection intensity was 565 per fish infected. In 2020, CsMc were detected in 206 (62.2%) out of 331 fishes in 10 species, and the infection intensity was 751 per fish infected. The other zoonotic trematode, ie. Metagonimus spp., Centrocestus armatus, Echinostoma spp. and Clinostomum complanatum, metacercariae were also detected in fishes from the survey streams, but their endemicities were relatively low. Conclusively, it was first confirmed that CsMc are highly endemic in fishes from Yongjeon-cheon in Cheongsong-gun, Gyeongsangbuk-do, Korea.
