This study was conducted to serve as a basis for education by identifying the correlation of college admission type, college-life satisfaction and academic achievement of radiologic science students. Data were collected from 2 universities and 2 colleges located in Gyeonggi Provice, North Chungcheong Province, North Gyeongsang Province. A total of 371 questionnaires were collected, 363 of which were included in this study. The results showed that there were no differences in academic achievement according to the type of college admission. It could be able to interpret that since department of radiologic science is popular, students with high academic records applies the department of radiologic science and there are less deviation of academic records among students. A correlation analysis of academic achievement showed learning attitude is a statistically valid factor. Learning attitudes can be changed by exposure to the environment. This will require a variety of program development for improving learning attitudes. In addition, academic achievement of radiologic science students is associated with license acquisition. It need to be made together research on determinants and development of learning method to improve the learning attitude.

This research obtained fundamental data for the development of grape foods by investigating the preference for grape foods, popularization and commercialization plan of grape foods and obtained knowledge required in order to develop grape foods. The study used 354 consumers in Seoul and GyeongGi Province. The distribution of sex on research subjects was as follows. Male was 52.0% (184 persons) and female was 48.0% (170 persons). Age distribution varied by twenties and less than twenties being 30.8%, thirties being 26.3%, forties being 24.6% and the fifties and over being 18.4%. According to the results, preference for grape foods of subjects was that rice wrapped in grape leaves ($2.14{\pm}0.7$) and sweet steamed rice($2.12{\pm}0.8$) were the highest among staple food; grape vinegar($2.38{\pm}0.7$) and grape taffy($2.25{\pm}0.7$) were the highest among spices; grape jelly ($2.53{\pm}0.6$) and grape pudding($2.45{\pm}0.7$) were the highest among snacks; grape juice ($2.70{\pm}0.5$) and grape yogurt($2.59{\pm}0.6$) were the highest among beverages. Subjects responded to the fruit group among food groups harmonized with grape foods(p<0.01). 50.7% of subjects responded to "have to be delicious" and 25.1% of subjects responded to "nutritional balance" as the most important aspects of the development of grape foods. In the popularization and commercialization plan of grape foods, Subjects chose with respected importance, personal preference($4.15{\pm}0.8$), price($4.05{\pm}0.8$) and promotional strategy($4.00{\pm}0.9$). In conclusion, the food development and revitalization plan should use grapes to find out food materials suitable for grape mixture and nutritional balance. We will expect an increase population and commercialization of grape foods if we develop grape foods and promote strategically in consideration of the preference of consumers and the price of produce.

On the basis of vegetation data collected by point-centered quarter method in analysis in Baekdudaegan of Gangwon province in the area of Hyangrobong, Odaesan, Seokbyeongsan, Dutasan, Deokhangsan and Hambaeksan, the study was carried out to classify forest communities and to evaluate the successional trends. The classification method of cluster analysis was used to make various disordered forests into several common groups for 1,004 sample points all together. By clustering the forests in the six study areas were classified into 28 forest communities, which were subjected to aggregate 8 representative forest communities on the count of species composition and species diversity. They were Mesophytic mixed forest community, others deciduous forest community, Quercus mongolica (dominant) community, Q. mongolica (pure) community, Pinus densiflora - Q. mongolica community, P. densiflora community, Betula ermanii community and Q. mongolica - Pinus koraiensis community. The ecological outlook from the result indicated that P. densiflora community and P. densiflora - Q. mongolica community, which were located in Seokbyeongsan, Dutasan and Deokhangsan around 1,000m above the sea level showed lower species diversity index. On the contrary Mesophytic mixed forest community, others deciduous forest community which was located in Hyangrobong, Odaesan and Hambaeksan mostly in protected area and national park around 1,500m above the sea level displayed higher species diversity index. As the composition ratio of Q. mongolica within a certain community was decreased, the species diversity was generally increased, assumed that abundance of Q. mongolica might be negatively associated with species diversity in the national deciduous forest.

The Seokgaejae section is located along a timber access road and a driveway across Bonghwa County, North Gyeongsang Province, and Samcheog city, Gangwon Province. Its stratigraphic column shows all of the ten strata of the lower Paleozoic Taebaek Group, Joseon Supergroup. The Seokgaejae section is proved to be scientifically important. Thirty-eight domestic/international journal papers have been published on this early Paleozoic stratigraphic site, and many distinguished researchers over the world have visited the site. However, the section has never been considered to be designated as a national natural monument and was not included in the adjacent Gangwon Paleozoic National Geopark due to management or administrative issues. Although the Seokgaejae section sufficiently satisfies many of the national natural monument criteria, designation for the natural monument may not be justified because of the facts that the outcrop was artificially exposed by road construction; the chance of destruction of the outcrop is relatively few; demage on the outcrop to some extent does not impair the intrinsic value of the section; and the geomorphological/landscape value of the section is low. The application of the recently modified geological heritage assessment model to the Seokgaejae section shows very high scores on the scientific/educational, intrinsic, and functional values. Based on the improved geological heritage grade standard, the Seokgaejae section conforms to the national-level protection criteria. It is strongly recommended to manage the Seokgaejae section as a principal geosite by including it in the Gangwon Paleozoic National Geopark. This case study on the Seokgaejae section also suggests that the process of application and endorsement of a national geopark need further improvement. As well as the improvement of the system or policy related to geological heritages, further efforts of the experts in various fields of geoscience are required in order for other geological heritages not to be neglected from now on.

This paper analyzes the distribution of water vapor pressure and relative humidity in complex terrains by collecting weather observation data at 6 locations in the valley in Jungdae-ri, Ganjeon-myeon, Gurye-gun, Jeolla South Province and 14 locations in Akyang-myeon, Hadong-gun, Gyeongsang South Province, which form a single drainage basin in rural and mountainous regions. Previously estimated water vapor pressure used in the early warning system for agrometeorological hazard and actual water vapor pressure arrived at using the temperature and humidity that were measured at the highest density (1.5 m above ground) at every hour in the valley of Jungdae-ri between 19 December 2014 and 23 November 2015 and in the valley of Akyang between 15 August 2012 and 18 August 2013 were compared. The altitude-specific gradient of the observed water vapor pressure varied with different hours of the day and the difference in water vapor pressure between high and low altitudes increased in the night. The hourly variations in the water vapor pressure in the weather stations of the valley of Akyang with various topographic and ground conditions were caused by factors other than altitude. From the observed data of the study area, a coefficient that adj usts the variation in the water vapor pressure according to the specific difference in altitude and estimates it closer to the actual measured level was derived. Relative humidity was simulated as water vapor pressure estimated against the saturated water vapor pressure, thus, confirming that errors were further reduced using the derived coefficient than with the previous method that was used in the early warning system.

At the age of 15, Song Gyu, the second patriarch of Won Buddhism, met Jeungsan-gyo members and was substantially influenced by them. Jeongsan cultivated himself for three months in Mount Gaya based on their recommendations. He instructed his family members to practice reciting the Tae-eul Mantra. Henceforth, Jeongsan was said to attain supernatural power when he was around 18 years old, and he pursued the traces left by Jeungsan in Jeolla Province. Once there, he asked Jeungsan's younger sister to move to his hometown, Seongju, Gyeongsang Province, and he served her with his utmost sincerity. He went back to the birthplace of Jeungsan and received a Daoist book from Jeungsan's daughter titled, Essentials for an Upright Mind (正心要訣). Jeongsan practiced holy works for 10 months at Daewon-sa Temple in Mount Moak where Jeungsan was said to have attained unification with the Dao. After he had met Jeungsan-gyo members at the temple, he was able to stay in her house where he ended up meeting So Taesan. Before their meeting, it is obvious that Jeongsan was a member of Jeungsan-gyo. Afterward, Jeongsan entered into Won Buddhism and used the passage, 'saving lives by curing the world (濟生醫世).' He recited the writing of Jeungsan, which had been given to his disciples, as if it had been a mantra. In addition, he mentioned Jeungsan's poems or the Chinese poems that he had quoted many times. Jeongsan also interpreted passages from The Hyunmu Scripture (玄武經) written by Jeungsan in a unique manner. Jeongsan answered his disciples in his own way when they asked questions on the teachings of Jeungsan. He recognized Jeungsan as one of the Three Primes, who presided over the Great Opening.

This study suggested a citizen science based model to enhance the efficacy of the managing invasive alien plants and examined whose applicability in 3 Wetland Protected Areas (Jangrok of Gwangju metropolitan city, Madongho of Goseong in South Gyeongsang Province, and Ungok of Gochang in North Jeolla Province). The process consists of (a) collecting citizen scientist including local residents of 3 protected areas and piling up information on the 4 species of invasive alien plants (Sicyos angulatus L., Solanum carolinense L., Ambrosia artemisiifolia L. and Solidago altissima L) in a information platform Ecological Information Bank (EcoBank) from September 18th to October 31th, (b) constructing distribution map containing the location and density (3 phases: individual-population-community) of target plants, (c) providing distribution map to Environment Agency and local government who is principal agent of managing invasive alien plants in 3 protected areas, and from whom (d) surveying applications of the distribution map and opinion for future supplement. As a result, citizen science based monitoring should be continued to complement the nationwide information for the field management of invasive alien plants with the expansion of target species (total 17 plants species that Ministry of Environment in South Korea designated) and period of monitoring in a year to increase the usability of surveyed information from citizen science. In the long run, effectiveness of the management of invasive alien species applied by citizen science should be reviewed including efficacy of field management process from citizen's participating in elimination project of invasive alien plants and time series distribution followed by the management of the species.

This study was carried out to investigate the effects of addition of citron peel powder(0.3%, 0.6%, 0.9%) on the quality characteristics of emulsion-type sausages. The pH, color, TBARS, residual nitrite content and textural properties were evaluated. The pH values of sausage containing citron peel powder were significantly(P<0.05) lower compared to those for control. The CIE $L^*$ and $a^*$ values of sausage containing citron peel powder tended to similar to control, but the CIE $b^*$ values were significantly(p<0.05) higher in the sausage containing citron peel powder. The TBARS values of sausage containing 0.9% citron peel powder were significantly(P<0.05) lower than those of control at 20, 40 and 60 days of storage. The residual nitrite content of sausage containing citron peel powder were significantly(P<0.05) lower compared to control. The hardness values of sausage containing citron peel powder were significantly(P<0.05) higher than those of control, but the cohesiveness, springiness and gumminess were significantly(P<0.05) lower in the sausage containing citron peel powder.

Pork from Jeju black pig (population J) and Berkshire (population B) has a unique market share in Korea because of their high meat quality. Due to the high demand of this pork, traceability of the pork to its origin is becoming an important part of the consumer demand. To examine the feasibility of such a system, we aim to provide basic genetic information of the two black pig populations and assess the possibility of genetically distinguishing between the two breeds. Muscle samples were collected from slaughter houses in Jeju Island and Namwon, Chonbuk province, Korea, for populations J and B, respectively. In total 800 Jeju black pigs and 351 Berkshires were genotyped at thirteen microsatellite (MS) markers. Analyses on the genetic diversity of the two populations were carried out in the programs MS toolkit and FSTAT. The population structure of the two breeds was determined by a Bayesian clustering method implemented in structure and by a phylogenetic analysis in Phylip. Population J exhibited higher mean number of alleles, expected heterozygosity and observed heterozygosity value, and polymorphism information content, compared to population B. The $F_{IS}$ values of population J and population B were 0.03 and -0.005, respectively, indicating that little or no inbreeding has occurred. In addition, genetic structure analysis revealed the possibility of gene flow from population B to population J. The expected probability of identify value of the 13 MS markers was $9.87{\times}10^{-14}$ in population J, $3.17{\times}10^{-9}$ in population B, and $1.03{\times}10^{-12}$ in the two populations. The results of this study are useful in distinguishing between the two black pig breeds and can be used as a foundation for further development of DNA markers.
