Externally, there is urgent need Strengthening the competitiveness of agriculture in terms of production, processing and consumption. And development of high-quality services is particularly essential for provide safe food to consumers, internally. We studied the concept of service science, service models and service development methodology, then researched strengthening agricultural competitiveness through analysis of service viewpoint. After then, in the service level and service science, we elicit the service components for the defined new business, which is composed of private service and supporting service for Mungyeong omija industry. In this research, we evaluate the possibilities that agriculture is not primary industries but service industries for competitiveness. We suggest four key service composition for win-win strategy in Mungyeong omija industry. That is authenticity service, decision price service, decision rating service, establish infrastructure for year-round sale.

We carried out the sensitive high resolution ion microprobe (SHRIMP) zircon U-Pb age dating and whole-rock geochemical analysis of granitoids and felsic porphyries in the Ssangyong Valley, Yongchu Valley, and Mungyeong Saejae geosites in the Mungyeong Geopark. The igneous rocks crop out in the western, northwestern and central parts of the Mungyeong city area, respectively, and intruded (meta)sedimentary successions of the Ogcheon Metamorphic Belt, Cambro-Ordovician Mungyeong Group and Jurrasic Daedong Group. The U-Pb isotopic compositions of zircon from two felsic porphyries and one granite samples in the Ssanyeong Valley yielded the Cretaceous intrusion ages of 93.9±3.3 Ma (tσ), 95.1±4.0 Ma (tσ) and 94.4±2.0 Ma (tσ), respectively. On the other hand, a felsic dike sample and a granite in the Yongchu Valley and a porphyritic granite in the Mungyeong Saejae had intrusion ages of 90.2±2.0 Ma (tσ), 91.0±3.0 Ma (tσ) and 88.6±1.5 Ma (tσ), respectively. Based on the average standard error calculated in combination with results of previous studies in this area (Lee et al., 2010; Yi et al., 2014; Aum et al., 2019), the geochronological results show that spatial variation in intrusion age of ~5 Myr between the Ssangyong (94.5±0.2 Ma) and Yongchu Valleys (89.7±0.4 Ma) is apparent. The geochemical compositions of major and trace elements in the samples showed an affinity of typical post-orogenic granite, indicating their petrogenesis during the late stage of Early Cretaceous magmatic activity possibly in association with subduction events of the Izanagi Plate.

In this study, Green apple from Mungyeong area was used as material in the fermentation process. In apple fruit growing process, to produce a high quality apple fruit, some Green apple should be removed. Since the removed Green apple fruit is inedible, it doesn't have any economical value. To solve this problem, this paper proposed fermentation process to increase the economical value of raw apple as a fermentation product. This research conducted seven days, and the pH and brix value analysis was done every 12 hours during fermentation process. The experimental results show that the fermentation product under blender treatment is better than cutting treatment and without cutting treatment. Initial brix 25% is the best treatment for fermentation because produce fermentation product with a good taste and aroma than other treatment.

The Cretaceous granites are widely distributed in the studied area, Mungyeong-Sangju, which belongs to the southwestern part of the Ogcheon Folded Belt. The granites are characterized by medium-coarse grained, spotted miaroles, partly flow textures of biotite, aplitic dykes and pegmatitic pockets with druse. From the major compositions, the granites indicate peraluminous, calc-alkaline, salic and late stage products of differentiation. In the view of normative compositions of Qz-Ab-Or and perthitic alkali feldspar, they were formed under 1-4kb and $426^{\circ}-456^{\circ}C$ in acqueous conditions. The K/ Ar biotite age shows $72{\pm}1$ Ma for this grante, corresponding to the igneous activity of the Bulgugsa Disturbance periods in the area. The above results represent that these granite bodies are differentiated from a single magma.

The studied Cretaceous granties are widely distributed at the southern Mungyeong area in the southwestern part of Ogcheon Fold Belt. From the mineralogical and geochemical compositions, it is suggested that they show the characteristics of I-type and magnetite-series and formed under the conditions of high oxygen fugacity. The mineral chemistry of plagioclase, alkali feldspar and biotite in the granites by EMPA, was revealed as albite to oligoclase, microcline to microcline perthite and orthoclase perthite, and annite compositions, respectively. The granites have the distribution patterns of enriched LREE and depleted HREE, and show Eu negative anomalies suggesting mainly due to the feldspar fractionation in the residual magma. The geochemical data of Eu, EU/$^*Eu$, Sm and Gd suggest that the granites of the area have more abundant alkali feldspar crystallization than plagioclase. From the geochemical characteristics of Sr/Ba, La/Sm vs. Ce/Yb and other trace element evidences, the granites were the late stage products of differentiation and fractionated from a homogeneous parental granitic magma.

The objectives of this study were to investigate soil chemical properties for forest rehabilitation and suggest design and management in abandoned coal mine areas in Mungyeong, Gyeongsangbuk-do. Total study sites were 10 sites, and soil analysis particular were soil pH, TOC, total-N, C/N ratio, A.v. $P_2O_5$, and CEC. Because most of study sites showed soil pH from 5.0 to 7.0, it seems that soil pH does not affect growth of vegetation. But soil pH in Danbong1 was acidic (pH 4.6), so it is needed to improve with ameliorant such as limestone. Most of study sites is necessary to manage for organic matter and Nitrogen, because there sites showed lower value of TOC and total-N than general forest. The values of A.v. $P_2O_5$ and CEC were good in most of study sites, so it seems that they do not have effect on vegetation growth. All of soil factors has no regression according to elapsed time after rehabilitation. TOC, total-N and A.v. $P_2O_5$ among soil properties have positive relationship between each other. It is necessary to fertilizer for organic matter and Nitroge because of value in TOC, total-N and C/N ratio. The results of this study were analyzed only one time. So, long-term monitoring for soil properties is important for the correct forest rehabilitation and management.

Objectives : Lysimachia mauritiana Lam. is known as a medicinal plant native to Korea that has antioxidant, anticancer, antibacterial, and antiviral activities. However, until now, research on the cultivation technology of L. mauritiana is insufficient, and there are no research data on the systematic cultivation method and mass production of L. mauritiana. Therefore, this study aims to establish a cultivation system of L. mauritiana. Methods : The cultivation environment of open land and facilities according to the growth of L. mauritiana was compared and tested. In addition, the equivalence of the origin collection extract and the cultivation extract was evaluated through Ultra high performance liquid chromatography (UHPLC) patterns analysis according to cultivation and comparison of the effect of inhibiting respiratory inflammation using BEAS-2B human bronchial epithelial cells. Results : The cultivation technology system was established through cultivation research of L. mauritiana raw materials. In addition, as a result of comparing and evaluating the equivalence of cultivated plants and L. mauritiana raw materials for suppressing respiratory inflammation, the same results were confirmed, and the equivalence was confirmed as a result of analyzing the UHPLC pattern with L. mauritiana raw materials. Conclusions : This study suggests that extract from cultivation research of L. mauritiana plants, which are native to Korea, can be used as a health functional food or medicine to improve respiratory health.

While the lecture activities in Simwonsa, Ganjae Jeon Wu(1841~1922) has established a "law of lecture activities" which was an ritual between a teacher and pupil, between the couple. Through this way he expected to recover the former ritual, even within their own school. In 1884 he built a "law of Sidong school", meaning to build a large object, elementary scholarship will serve as the rules of conduct, and argued that human nature mainly served to the core in the course of study. Ganjae in Mungyeong area was also discussing studies with Song Byeong-hwa(1852~1916) and received correspondence with scholars in areas related to Mungyeong. They were Kim Jae-kyung(1841~1926) and Park Se-hwa (1834~1910). Ganjae had also some big national events on the sojourn time in Mungyeong. In 1882 there were army incident, in 1884 there were a command of the government that people must pull on western clothes. Ganjae did not follow the command of the government. Someone asked "Can we not follow the command of the government?" Ganjae replied "We have a right to resist to the illegal command of the government. There were also 1884's Gapsin-coup, Ganjae saw that we must defend the country by rejecting foreign power and keeping our rituals. Given the above, the timing that Ganjae lectured in Mungyeong personally was a time that provided a clue to establish his core ideas. Nationally it was a time that must defend the country from foreign nations. Ganjae had faith that for keeping the country we must keep firmly our own rituals.
