  • In the vine training methods, main vine training yield was 36% higher than the non-training. Main vine training date was studied for increasing cone yield in hops. Training was done four different dates from May 14 to May 29 including non-training as a check. Earlier training increased cone yield from 12 to 43% due to more beared branches per plant, longer branch length caused by accelerating the branch growth, and an increased of number of cone per beared branch and total cone number.

  • Haeju was home to the Hwanghae-do Provincial Office and a hub for supporting the northwestern regions of Korea. Local commerce expanded in Haeju during the late Joseon period based on its abundant resources and regional products, leading it to evolve into a large city. King Seonjo temporarily resided in Haeju while seeking refuge from the Japanese Invasions of Korea, and Yi Yi (sobriquet: Yulgok) secluded himself in Seokdam in Haeju in his later years. King Seonjo's residence in Haeju and Yi Yi's retirement there boosted interest in the city among the literati and influenced its places of scenic beauty. The development of its local history and literary achievements were documented in a wide variety of historical records and visual materials. Eight scenic views in Haeju became famous through a poem written by Seong Su-ik in the late sixteenth century. Around the mid-eighteenth century, eight new scenic views became popular. Local officials and travelers from other regions produced a vast body of prose and poetry focusing on the landscape and society of Haeju, playing a crucial role in raising awareness of its scenic attractions. Most surviving visual materials related to Haeju were created in and after the nineteenth century. Many of them illustrate both landscapes and the everyday lives of people. Among them, paintings of scenic spots created by Jeong Seon (sobriquet: Gyeomjae), who never actually visited Haeju in person, raises some of the issues posed by relying on indirect materials. In contrast, Eight Scenic Views of Haeju, which is presumed to have been produced by a local painter, appears to have accurately highlighted the characteristics of each scenic spot. Moreover, Haejudo, a folding screen presenting a panoramic view of Haeju, incorporates content from paintings depicting eight scenic views, in this case Eight Scenic views of Haeju. This practice can be observed in visual materials of other provincial cities.

  • As a part of epidemiologic investigation of tsutsugamushi disease, the wild rodents which were captured in Gyeongnam area were diagnosed with indirect immunofluorescent antibody assay (IFA) and Polymerase Chain Reaction (PCR) to find if they have an antibody against Orientia tsutsugamushi. The conclusion was drawn as followings. (1) The captured 58 wild rodents showed that the subspecies distribution of Apodemus agrarius was 86.2%, Microtus fortis was 8.6% and Crocidura lasiura was 5.2%. (2) The antibody positive rate of O. tsutsugamushi Gilliam, Karp, Karto and Boryong by IFA method was 32.0% in Apodemus agrarius among 50 wild rodents and 40.0% in Microtus fortis among 5 wild rodents, respectively. It was negative in the case of all the 3 Crocidura lasiura. (3) The antibody titers on Apodemus agrarius, Microtus fortis and Crocidura lasiura against Gilliam, Karp, Karto and Boryong were measured between 1:20 and 1:640. The antibody titer against each antigen was in the order Boryong>Gilliam>Karp. (4) O. tsutsugamushi was detected from the blood, spleen and kidney from the artificially infected mice by IFA and PCR. IFA showed the positive response between 3 and 18 days after inoculation. On the other hand, positive response was found from all the samples by PCR. (5) From PCR of the genomic DNA extracted from the blood, spleen and kidney samples of the captured wild rodents, Boryong-specific amplification product with size of 210 bp, which is particular in Boryong, was detected from spleen and kidney samples, but not detected in the blood. (6) Boryong-specific amplification product was detected from spleen and kidney samples which were obtained at 3, 6, 12, 18 and 24 days after the infection with Boryong. But, it wasn't detected from the uninfected samples. (7) From PCR of spleen and kidney samples of the captured wild rodents, it was found that positive rate of O. tsutsugamushi in Apodemus agrarius and Microtus fortis were 25.0% (4/16) and 20.0% (1/5), respectively. From the above results, it can be concluded that Apodemus agrarius resided in Gyeongnam area carried O. tsutsugamushi and PCR method might be a simple, precise, rapid and useful diagnostic tool than IFA for the diagnosis of O. tsutsugamushi.

  • This experiment was carried out to investigate the residue patterns of two insecticides, indoxcarb and thiamethoxam, commonly used for Chinese cabbage, under greenhouse conditions. The pesticides were sprayed onto Chinese cabbage at the recommended dose and double of the recommended dose 10 days before the prearranged harvest and then sampling was done at 0.17, 1, 2, 3, 4, 5, 6, 8, 10, and 12 days after spraying. The amounts of their residues in the crop were analyzed with an HPLC. The limit of detection(LOD) of both indoxacarb and thiamethoxam was 0.01 mg kg1 and mean recoveries of indoxacarb and thiamethoxam were from 97.91 to 104.36% and from 97.07 to 105.49%, respectively. Half-lives of indoxacarb and thiamethoxam were 3.4 and 2.3 days at the recommended dose and 3.3 and 3.5 days at the doubled dose, respectively. The ratios of the EDI to ADI by intake the crop harvested 10 days after spraying were less than 4% of their ADIs.

  • In order to elucidate the residual characteristics of some pyrethroid insecticides commonly used for Korean cabbage, such as bifentbrin, lambda-cyhalothrin and deltametbrin, the test pesticides were sprayed onto the crop at recommended rate and doubled rate of the recommendation. Their detection limits were 0.004 mg kg1 and mean recoveries at the fortification levels of 0.04 and 0.2 mg kg1 were from 95.16 to 99.32 and from 86.81 to 103.73%, respectively. Half-lives were from 2.5 to 3.6 at the recommended rate and from 2.3 to 3.9 days at the doubled rate of the recommendation. Initial residue amounts of bifenthrin and lambda-cyhalothrin at the recommended rate and doubled rate of recommendation and of deltamethrin at the recommended rate were less than their MRL, whereas, in case of deltamethrin sprayed at doubled rate of the recommendation, the residue level exceeded its MRL. However, the residue levels of the pesticides in the crop sampled at harvest were less than their maximum residue levels and the ratios of the estimated daily intake (EDI) to acceptable daily intake (ADI) for the pesticides tested calculated from the residue data at harvest were less than 7%, suggesting that these pesticides would be safe for Korean cabbage from the residue concern.

  • The concepts of activity involvement(AI) and place attachment(PA) are useful for explaining the sustainable use of natural resources by humans. Although several studies have investigated the effects of AI and PA on environmental behaviors and found its implications, it has not examined the simultaneous effects of both AI and PA. Thus, the purpose of this study was to develop a typology of both AI and PA. This typology was used to explain the environmentally responsible behaviors of visitors. The study sample surveyed 587 users of the main trail in Namhansanseong Provincial Park The results were analyzed by frequency, reliability, factor analysis, cross-tabulation, T-test, correlation and ANOVA analysis. As a result, the typology identified four subgroups of hikers based on involvement in hiking and attachment to setting. Results also indicate that environmentally responsible behaviors do vary significantly across typology. In detail, general environmental behavior and specific environmental behavior were significantly different between the four groups. These finding suggests that PA seems to play a more powerful role than AI in relation to environmental behavior. While more involved and more attached hikers were more active in environmental behaviors, less involved and less attached hikers had a more passive attitude. In this respect, this study placed emphasis on the fact that the future resource management of tourism and outdoor recreation may be established based on its activity experience in certain place.

  • Through the vegetation survey of Geumcheon Valley on the south-facing slope and the other side of the valley, Jedanggol on the north-facing slope in Taebaeksan Provincial Park, the characteristics of vegetation structure and change by slope and altitude were examined. From Geumcheon Valley(850m) via the ridge(1,380m) to Jedanggol(950m), thirty plots at intervals of 50m altitude were selected for investigation. According to the results of the analysis, Acer pictum subsp. mono, Fraxinus rhynchophylla, Betula davurica and Lindera obtusiloba were observed only in the south-facing slope, while Sorbus commixta, Prunus padus, Prunus maackii and Acer komarovii were observed only in the north-facing slope. However, Quercus mongolica, Betula costata, Cornus controversa, Tilia amurensis, Acer pseudosieboldianum and Magnolia sieboldii were found to be distributed over both the slopes. The analysis of ordination found that the vegetation was distributed discontinuously by slope. Especially, the vegetation of the north-facing slope appeared to be affected by the direction that the slope faces. Quercus mongolica community, which is the dominant species at an altitude of over 1,200m, was determined to be affected by elevation factor. The maximum age of the major trees was as follows: Betula costata and Quercus mongolica were estimated to be 53-year-old and 113-year-old respectively.

  • This study was conducted to compare and analyze forest vegetation distributed in Geumosanseong-inside in Geumosan Provincial Park from 2017.10 to 2019.6. The vegetation structure was classified by the phytosociological method and TWINSPAN and the correlation between the community structure and the environmental factors was analyzed using DCCA ordination analydsis. The vegetation structures are Quercus mongolica, Fraxinus mandshurica, Q. acutissima, Larix leptolepis, Prunus padus and Morus alba community by the phytosociological method and 16 communities under TWINSPAN. The importance value of Q. mongolica(64.5) was the highest, and followed by F. mandshurica, L. leptolepis, Acer pseudosieboldianum, M. alba, P. padus, Q. acutissima, Sorbus alnifolia, P. serrulata var. pubescens, F. sieboldiana, Rhododendron schlippenbachii and Castanea crenata which is consistent with species having the dominance status by analysis of the vegetation structure. As the results of DBH analysis for taxon with high importance values, Q. mongolica and M. alba represented normal distribution, and thus, the dominance status of these species is likely to continue. L. leptolepis will maintain the dominance status due to high density of large individuals as compared with species above medium size. However, it will decrease because of high mortality after increase in age class. F. mandshurica and P. padus continue to show dominance status due to high density of young individuals as compared with species above medium size. Q. acutissima have high density of individuals above intermediate size and low density of young individuals, and thus, will maintain the dominance status. A. pseudosieboldianum, F. sieboldiana and R.schlippenbachii which are arborescent will present continuously high dominance status because of high density of young individuals. Soil analysis shows that whereas pH, Ca2+ and Mg2+ in the research area were lower than the average values of overall forest soil and O.M, T-N, C.E.C and P2O5 were higher. We expected that these results were due to agricultures until 50 years ago in Geumosanseong-inside. As a result of DCCA ordination analysis using eleven environmental factors and communities classified by the phytosociological method analysis showed that Q. mongolica was distributed in the environment with higher elevation and O.M and steep slope, and lower P2O5, Mg2+ and Ca2+. In contrast to F. mandshurica, Q. acutissima was distributed in higher K+ and lower pH. L. leptolepsis was distributed in various environment.

  • This study examined visitors' perceptions and attitudes about establishing cable car in Mudeungsan Provincial Park (MPP). Data were collected from 401 respondents by a field questionnaire survey in MPP during the September of 2010. 61.7% of respondents opposed to establishing cable car in MPP while 20.6 percent supported it. Respondents showed high level of belief to possible consequences that establishing cable car will result in 'deterioration of ecosystem and natural landscape', 'crowding problem by increased number of visitors', 'disappearance of naturalness or previous nature experiences in MPP'. Respondents, however, presented low belief to 'positive effects on increasing economic income and local economic growth by attracting tourists'. 32.4 percent of the survey respondents evaluated the present MPP as a place of 'Nature Preservation Area (NPA)' and 10.5% as 'Developed Park Area (DPA)'. 48.8% of respondents answered that MPP should be managed as 'NPA' with only 2.5% as DPA. Respondents' socio-demographic characteristics (i.e., gender, age, education level, length of residence in Gwang-ju city), use patterns (number of visits to MPP or to Jungbong and surrounding areas), and normative place condition of MPP showed relationship with the overall support rates about establishing cable car. The results and their implications were discussed.
