Gyeongoggo is first described in the Collected Prescription by Hong Family in the Song Dynasty in China. It is composed of Radix Rehmnniae, Panax ginseng, Poria cocos, and Mel. Its main efficacy is to treat weakness of primordial essence of body and dry cough, and to invigorate qi and replenish yin principle. It is one of the most important prescriptions that people have been using for a long time. We studied the documents recorded in the medical classics and comprehended the following results. Gyeongoggo has efficacy to keep a person healthy and live long age, to treat amnesia and dizziness from brain weakness, to strengthen muscle and bone by improving function of stomach and colon, to improve a person's memory and judgement, to invigorate brain weakness, and, to treat tuberculosis and lung cancer. The longer a person take it, the better it is for one's health and meditation. When it is made, it is important to mix four components up, to boil it with an oak tree for three days and nights, and then to add water from a well to reduce heat for a full day, and to boil up again for a full day to mature fully. As gyeongoggo is acquired not only by the full heart of a manufacturer but also the sympathy of nature, it is important to choose a clean place to make and keep. When it is taken, it is proper to take it with warm water or liquors. And when it is made, we came to know that it is possible to make gyeongoggo with special efficacy by adding one to three more components.

The diversity of epiphytic bacterial communities on deciduous oak tree (Quercus dentate Thunb.) leaves was examined both in the natural forest area with a clean air and in the industrial estate to assess effects of acidic deposition to the phyllosphere using 16S rDNA sequence data. In addition, acid-tolerant epiphytic bacterial communities were compared. A total of 78 epiphytic and 444 acid-tolerant clones were obtained from clone libraries, resulting in 20 and 17 phylotypes by analysis of restriction fragment length polymorphism (RFLP) for PCR-amplified 16S rDNA products. A low bacterial diversity in both areas was found. As tree leaves grow older, bacterial diversities were slightly increased in the level of subphylum. The community structure of epiphytic bacteria in both areas in April consisted of only two subphyla, $\beta-and\;\gamma-Proteobacteria$. In August two additional subphyla in both areas were found, but the composition was a little different, Acidobacteria and Cytophaga-Flexibacter-Bacteroids (CFB) group in the industrial estate and a -Proteobacteria and CFB group in the natural area, respectively. Acidobacteria could be an indicator of epiphytic bacteria for acidic deposition on plant leaves, whereas a -Proteobacteria be one of epiphytic bacteria that naturally survive on leaves that are not affected by acidic deposition. The acid-tolerant bacterial communities in April were composed of two subphyla, $\gamma-Proteobacteria$ and Low G+C gram-positive bacteria in both areas, and in August a-Proteobacteria was added to the community just in the natural forest area. The direct influence of acidic deposition on the acid-tolerant bacterial phylogenetic composition could not be detected in higher taxonomic levels such as subphylum, but at narrower or finer levels it could be observed by a detection of Xanthomonadales group of $\gamma-Proteobacteria$ just in the industrial estate.

As a primary step to develop natural preservative for extending the shelf-life of kimchi, the effect of 102 edible plants, 21 antimicrobial agents and related compounds on kimchi fermentation was studied. Among 42 oriental medicinal plants tested, Baical skullcap and Assam indigo were found to be highly effective for maintaining the fresh state of kimchi. Although Bugbane, Red mangolia, Bushy sophora, Szechuan pepper, Chinese quince and Scisandre significantly inhibit the growth of Lactobacilli, their effect was not high enough to be used as raw materials for kimchi preservative. When the effect of 32 herbs and spices was tested, peppermint, cinnamon, lemon balm, clove, hop, rosemary, sage, horseradish and thyme showed high antimicrobial activity against kimchi microorganisms. Among them, the effect of clove ranked top. When it was added to fresh kimchi, initial cfu value ($2.4{\times}10^{6}cfu/g$) changed little even after 2 day's fermentation ($2.6{\times}10^{6}cfu/g$). Sensory test was not a good criteria to evaluate the effect of herbs and spices, since their highly specific flavors affected the taste of kimchies. Twenty eight fruits, vegetables and related plants were tested, but only leaves of pine tree, persimmon and oak leaves showed a significant bactericidal effect, finally contributing to the storage of kimchi. In addition, when 21 natural preservatives and other compounds were added individually to fresh kimchi, nisin and caffeic acid could inhibit fermentation.

Nickel substituted manganese ferrites, $Mn_{1-x}Ni_xFe_2O_4$ ($0.0{\leq}x{\leq}0.6$), were fabricated by sol-gel method. The effects of sintering and substitution on their crystallographic and magnetic properties were studied. X-ray diffractometry of $Mn_{0.6}Ni_{0.4}Fe_2O_4$ ferrite sintered above 523 K indicated a spinel structure; particles increased in size with hotter sintering. The M$\ddot{o}$ssbauer spectrum of this ferrite sintered at 523 K could be fitted as a single quadrupole doublet, indicative of a superparamagnetic phase. Sintering at 573 K led to spectrum fitted as the superposition of two Zeeman sextets and a single quadrupole doublet, indicating both ferrimagnetic and paramagnetic phase. Sintering at 673 K and at 773 K led to spectra fitted as two Zeeman sextets due to a ferrimagnetic phase. The saturation magnetization and the coercivity of $Mn_{0.6}Ni_{0.4}Fe_2O_4$ ferrite sintered at 773 K were 53.05 emu/g and 142.08 Oe. In $Mn_{1-x}Ni_xFe_2O_4$ ($0.0{\leq}x{\leq}0.6$) ferrites, sintering of any composition at 773 K led to a single spinel structure. Increased Ni substitution decreased the ferrites' lattice constants and increased their particle sizes. The M$\ddot{o}$ssbauer spectra could be fitted as the superposition of two Zeeman sextets due to the tetrahedral and the octahedral sites of the $Fe^{3+}$ ions. The variations of saturation magnetization and coercivity with changing Ni content could be explained using the changes of particle size.

In this study, cross-laminated wood panels were manufactured with four softwoods and three hardwoods with the goal of efficiently predicting the static strength performance using dynamic modulus of elasticity (MOE) and simultaneously revealing the dynamic performance of cross-laminated wood panels. The effect of the density of the species on the dynamic MOE of the laminated wood panels was investigated. Moreover, the static bending strength performance was predicted nondestructively through the correlation regression between the dynamic MOE and static bending strength performance. For the dynamic MOE, the parallel- and cross-laminated wood panels composed of oriental oak showed the highest value, whereas the laminated wood panels composed of Japanese cedar showed the lowest value. In all types of parallel- and cross-laminated wood panels, the density dependence was confirmed, and the extent of the density dependence was found to be greater in the P_⊥ and C_⊥ types with perpendicular-direction laminae in the faces than in the P_∥ and C_∥ types with longitudinal-direction laminae in the faces. Our findings confirmed that a high correlation exists at a significance level of 1% between the dynamic modulus and static bending modulus or bending strength in all types of laminated wood panels, and that the static bending strength performance can be predicted through the dynamic MOE.

This study investigated the resistance of domestic wood species used as wood members in general wood construction and Korean wood cultural properties to the termite Reticulitermes speratus using no-choice and two-choice tests. The results of the no-choice experiment confirmed that hardwood has higher termite resistance than that of softwood. In addition, R. speratus prefers softwood, including Abies holophylla, which has low density, is easy to feed on, and does not contain repellent extracts. In a two-choice test, Zelkova serrata was found to be the most termite-resistant wood species used in wooden cultural buildings. In addition, we investigated the effects of different wood extraction methods and their components on termite resistance. The cold-water extraction of softwood increased the feeding activity of termites; however, the cold-water extraction of hardwood had little effect on the feeding activity of termites. In natural environments with repeated exposure to moisture, such as rainfall, water-soluble extracts present in wood species are relatively more likely to dissolve and removed, making softwood more likely to be damaged by termites than hardwood. Untreated Quercus variabilis showed an extremely weak feeding activity of termites compared with that in other wood species; however, feeding termites with the alcohol-benzene extract of Q. variabilis had no inhibitory effect on their feeding activity. Therefore, we believe that the high density of Oriental cork oak wood inhibits the feeding activity of R. speratus. In contrast, the alcohol-benzene extracts of Z. serrata, Prunus sargentii, and Castanea crenata showed a strong inhibition of the feeding activity of termites.

1874년 박규현이 기술한 '파산서당기'를 중심으로 분석한 파산서당의 영건과정과 조경식물의 변화상을 추적한 연구결과는 다음과 같다. 첫째, 대구 달성의 하빈면 묘리 파회에 자리한 살림집 삼가헌과 별당(파산서당)은 사육신 박팽년(1417~1456)의 11대손 박성수로부터 14대손 박규현에 이르기 까지 약 90년간(1783~1874)에 걸쳐 완성되었는데, 풍수적 회룡고미형(回龍顧尾形)으로 회자되는 길처이다. 둘째, 파회마을은 박성수가 1769년(영조 45)에 벗들과 교우하기 위해 초가를 짓고 자신의 호(삼가헌(三可軒))를 당호로 삼은 것으로부터 유래하는데, 둘째아들 박광석이 분가(1783)한 후 사랑채(1826)와 안채(1869)를 지었고, 박광석의 손자 박규현이 1874년에 연을 심어 가꾼 연못과 정자(하엽정)를 추가했으며, 파산서당 명칭은 삼가헌 뒷동산 지명과 연계된다. 셋째, 네모꼴 연못은 길이 21m, 너비 15m 규모로 연꽃을 심었는데, 못 가운데 원형 섬을 두어 조선시대의 보편적인 성리학적 세계관을 반영하고 있다. 파산서당에 부가된 정자(하엽정)의 명칭, 동쪽 방 이연헌(怡燕軒), 서쪽 방 몽양재(蒙養齋) 등은 군자적 삶의 염원, 그리고 자손들의 밝은 미래를 염원하는 뜻을 담았다. 넷째, 성리학적 규범(소나무, 연꽃, 대나무), 안빈낙도의 생활철학(버드나무), 은일사상과 태평성대의 염원(대나무), 그리고 구휼목적과 실용성(밤나무, 상수리나무, 가래나무, 옻나무 등)에 비중을 둔 식재수종의 반영을 추적할 수 있는데, 이는 서당이라고 하는 장소성과 상징성, 절제미학 등을 고려한 조경법이라 하겠다. 다섯째, 조영초기 식재수종은 회화나무와 연꽃을 제외하고 대부분 고사하여 다른 수종으로 대체되었는데, 서당 기능의 상실과 풍수적 가치(홍동백서 상징수종), 벽사기능(엄나무와 탱자나무), 심미성 및 실용적 가치(해당화, 매화, 배나무, 복숭아나무, 굴참나무), 가문의 번영과 변화지 않는 청백의 삶(자귀나무, 배롱나무, 주목), 심미관 등 후손들의 확장된 작정관을 보여주는 사례이다.
