  • The wooden fence(木柵), which began to appear in the Bronze Age and is presumed to be the oldest defense facility in human history, was used as a fortress for the purpose of further strengthening military defense functions until after the Japanese Invasion of Korea in 1592 in the Joseon Dynasty(壬辰倭亂). As it was established as the concept of a fortress or a fence installed outside a fence castle(城柵) or barracks fence(營柵), its importance as an essential facility for defense was further highlighted. This study is the result of exploring wooden fence that were used as official facilities during the Joseon Dynasty, focusing on literature surveys such as 『Annals of the Joseon Dynasty』 and 『New Jeungdonggukyeojiseungram』 In this study, in particular, the conclusion of this study is as follows, focusing on the use and function of Nokgakseong(鹿角城), underwater wooden fence, installation methods, and materials of wooden fences, is as follows. The conclusions of this study, which focused on the materials of the wooden fence, are as follows. First, as invasions by foreign enemies became more frequent in the late Goryeo and early Joseon Dynasty, wooden fences played a major role as a major out-of-castle defense facility((防禦施設). In addition, wooden fences were modified and installed into various types such as wooden fences(木柵城), Nokgakseong, a fence made up of large branches in the shape of a deer antler, and underwater wooden fences(水中木柵) according to the circumstances of the times, government policy, and location environment. Second, wooden fences were installed in strategic locations in defense facilities for military purposes, such as mountain fortress(山城), fortresses(營), camps(鎭), forts(堡), and castles(邑城) in strategic locations, and were used for defense in case of emergency. According to the urgency of farming, it was installed in accordance with the non-farming season, when it is easy to mobilize manpower to avoid the busy farming season. The size of the wooden fence of the Joseon Dynasty, which are confirmed through literature records, was converted into Pobaekchuk(布帛尺), and the circumference was very diverse from 4,428chuk(2,066m) to 55chuk(25m). Third, Nokgakseong is an efficient combat support facility that is more aggressive than a general wooden fence, and the records of Nokgakseong in the Annals of the Joseon Dynasty appeared during the King Sejong period the record was 20 times, the most. By region, it was found that it was mainly installed in coastal rugged areas such as Pyeongan and Hamgildo(12), which are the 6-jin areas of the 4th Army. Fourth, in the early 15th century, as the royal court established a maritime defense strategy for the coastal area of the southern coast, after the Sampo Invasion(三浦倭亂), riots by Japanese settlers in Sampo in 1510, major military posts including eupseong(邑城), camps, and forts were established. The installation of underwater barriers around various government facilities rapidly increased as a defense facility to block the warships of Japanese pirates around various government facilities. Fifth, between the 15th and 17th centuries before and after the Japanese Invasion of Korea in Sampo, underwater fences were installed in the Southern coast and Ganghwa Island. In particular, in the 15th century, underwater fences were intensively installed in coastal areas of Gyeongsangnam-do, such as Jepo. Pine trees and Oaks are the main materials used for underwater fences, but other materials such as Oldham's meliosma, Loose-flower hornbeam and The vines of arrowroots were also used as materials for wooden fences.

  • Pollen analysis from lake districts, Youngnangho, Wolhamji and Bangeojin, revealed vegetational patterns in Korea. The pollen stratigraphy was divided into five zones, zone L, I, II, IIIa and IIIb for the past 15,000 years. During zone L (earlier than 10,500 yr BP), late-glacial period, Youngnangho was vegetated with a coniferous forest dominated by spruce, larch, haploxylon pine and fir with considerable amount of herbs. Zone I(10,500~7500 yr BP) was predominantly herbaceous vegetationj with significant amount of oak and diploxylon pine. It suggests that the overall environment became milder and drier than late-glacial period. Zone II(7,500~4,000 yr BP), hypsithermal period, showed significant warming condition, indicated by high pollen concentrations of oak, diploxylon pine and hornbeam, and by more diverse flora of deciduous broad-leaved trees than before. Herbs were not an important part of vegetation. Zone III$^a$(4,000~1,500 yr BP) had pine and oak as main elements. Birch increased slightly while hornbeam decreased in this time. It indicates cooling condition. Zone III$^b$(1,5000-present) which can be called pine period showed obvious human interference. Following forest clearance, agriculture was intensified. The beginning of logging and agriculture was discernible by a sudden decline of arboreal species and by considerable amount of rice, buckwheat, sorrel and plantain. Numerous charcoal fragments were observed in zone I and zone III$^b$.

  • 하계 동해의 남서부해역에 냉수가 왜 그리고 어떠한 해양환경하에 출현하는가를 밝히기 위하여 현장조사, 위성자료의 분석 및 수치실험을 실시하였다. 이 해역에서 냉수는 비정상년의 경우는 정상년에 비해 보다 더 연안 가까이에서 출현하였고, 수온도 낮았다. 이것은 냉수가 비정상년에는 정상년에 비해 크게 발달하여 연안역으로 확장함을 의미하였다. 흐름장의 계산결과는 지형류적인 관점에서 수온의 관측결과를 잘 재현하였다. 한편, 정상년의 경우는, 북한한류(NKCW)가 쓰시마난류(TC)와 균형을 유지하면서 동해의 북서쪽에 머물고 있었다. 이에 반해, 비정상년의 경우는, 북한한류가 점차 남쪽으로 남하하여 동해 서부역의 대부분이 북한한류의 세력하에 놓였다. 그래서, 하계 동해 서부 연안역에서의 냉수 출현은 남쪽으로의 북한한류의 확장에 의한 부산물인 것으로 판단되었다. 울산 연안역에 대한 유동계산결과는 하계 남풍이 불 경우, 표층과 저층 사이에 흐름의 역전현상이 나타났다. 따라서, 하계 동해의 남서부 연안역, 특히 수심의 변화가 급한 방어진 부근에서 냉수의 용승이 일어날 수 있음을 시사하였다.

  • The effect of Neobacillus sp. JC05 extract on the defense response in cucumber plants against root-knot nematode (RKN) was evaluated. As a result of drench treatment of JC05-extract in cucumber plants, formation of egg mass per plants and disease severity were significantly decreased compared to untreated control plants; the malondialdehyde contents also decreased in JC05-extract treated plants. When eggs of Meloidogyne incognita were inoculated, cucumber plants treated with JC05-extract elevated pathogenesis-related gene expression such as chitinase and lipoxygenase, these are well known as inducing resistance in plants, in addition, peroxidase among antioxidant enzymes was significantly activated. Moreover, the JC05-extract enhanced FDAse activity in soils grown cucumber plants inoculated by eggs of M. incognita. Taken together, these results suggest that the JC05-extract could involve in activation of defense-related mechanisms of cucumber plants and result in decrease of disease occurrence caused by M. incognita.

  • This study is a study to examine and verify the importance of human resources among the various factors that modern companies need to consider in order to cope with the changing environment. As independent variables, acquiescent and defensive silence were composed of the motives felt by members, and creativity and innovation behavior were set as the outcome variables. Through this research, first, the importance of communication between the members of the organization and the manager is investigated, and it is intended to be managed efficiently. Secondly, we would like to confirm the modulating effect of resilience in the relationship between them, and to find out the importance of psychological recovery of members. In the end, this aims to talk about the importance of psychological management and recovery of members in managing human resources. As a result, acquiescent silence negatively affects creativity and innovation behavior, and defensive silence positively affects creativity and innovation behavior. In addition, in the case of the moderating effect of resilience, there was no significant relationship in both defensive silence, creativity, and innovation behavior, and in the case of acquiescent silence, only innovation behavior was found to be significant. This is the result of the combination of the unique characteristics of resilience and the difference in the disposition of the members who choose resignation silence and defensive silence.
